Стандартный вид числа | Алгебра

Стандартный вид числа — это запись числа в виде произведения:

x · 10ⁿ,

где  1 &les; x < 10,  n  — целое число.

С помощью целых показателей степени числа 10 можно записывать очень большие и очень маленькие числа в стандартном виде, то есть громоздкие записи заменять краткими. Рассмотрим несколько примеров записи чисел в стандартном виде:

56000 = 5,6 · 10⁴;

314,7 = 3,147 · 10²;

5400000000 = 5,4 · 10⁹;

0,00038 = 3,8 · 10^-4.

Обратите внимание, что в стандартном виде число, которое умножается на 10 в какой-либо степени, всегда должно быть больше или равно единице и меньше десяти. Следовательно, если мы перепишем наши примеры так:

56000 = 56 · 10³;

314,7 = 0,3147 · 10³;

5400000000 = 540 · 10⁷;

0,00038 = 38 · 10^-5;

то записи чисел хоть и будут выглядеть похожими на стандартный вид, но к числам в стандартном виде они не будут иметь никакого отношения.

Любое однозначное число в стандартном виде представляет собой произведение самого себя на 10 в нулевой степени:

1 = 1 · 100	6 = 6 · 100
2 = 2 · 100	7 = 7 · 100
3 = 3 · 100	8 = 8 · 100
4 = 4 · 100	9 = 9 · 100
5 = 5 · 100

Число 10 в стандартном виде равно произведению единицы на 10 в первой степени:

10 = 1 · 10¹.

Примечание: число 0 нельзя представить в стандартном виде.

Примеры. Запишите число в стандартном виде:

1) 2400;	5) 38;
2) 8600;	6) 387;
3) 0,00019;	7) 1280000;
4) 37000000;	8) 2370000.

Решение:

1) 2400 = 2,4 · 10³;

2) 8600 = 8,6 · 10³;

3) 0,00019 = 1,9 · 10^-4;

4) 37000000 = 3,7 · 10⁷;

5) 38 = 3,8 · 10¹;

6) 387 = 3,87 · 10²;

7) 1280000 = 1,28 · 10⁶;

8) 2370000 = 2,37 · 10⁶.

90000 Conversion Calculator 90001 90002 Use this Conversion Calculator to convert between commonly used units. Select the current unit in the left column, the desired unit in the right column, and enter a value in the left column to generate the resulting conversion. A full list of unit conversions is available at unitconverters.net. 90003 90004 90005 Different Systems of Units 90006 90002 Historically, many different systems of units have been used, where a system of units is defined as a collection of units of measurement with rules that relate them to each other.A unit of measurement is a defined magnitude of a quantity that it used as a standard for measurement for the same kind of quantity, such as measurements of length, weight, and volume. 90003 90002 In the past, many systems of measurement were defined on a local level, and could be based on factors as arbitrary as the length of a king’s thumb. While this may work on a local level, when considering trade, as well as science, having systems of units based on units that others may not be able to relate to or understand makes interaction difficult.As such, the development of more universal and consistent systems developed over time. Today, some of the systems of units in use include the metric system, the imperial system, and the United States customary units. 90003 90002 The International System of Units (SI) is the standard metric system that is currently used, and consists of seven SI base units of length, mass, time, temperature, electric current, luminous intensity, and amount of substance. Although SI is used almost universally in science (including in the US), some countries such as the United States still use their own system of units.This is partly due to the substantial financial and cultural costs involved in changing a measurement system compared to the potential benefit of using a standardized system. Since US customary units (USC) are so entrenched in the United States, and SI is already used in most applications where standardization is important, everyday use of USC is still prevalent in the United States, and is unlikely to change. As such, many unit converters including this Conversion Calculator exist, and will continue to do so to ensure that people globally are able to communicate different measurements effectively.90003 90005 History of the Pound 90006 90002 In the eighth and ninth centuries of the Common Era (CE), Arab civilization flourished in the Middle East and Spain. The Arabs used coins as a measurement of units of weight since a minted coin could not easily be cut or shaved to reduce its weight, and thus provided a measurable standard. They used a coin called a silver dirhem as a basic measure of weight, which had a weight roughly equivalent to 45 fully grown grains of barley. Ten dirhems comprised a Wukryeh which was translated into Latin as an «uncia» — the origin of the word «ounce.»90003 90002 Over time, trade spread from the Mediterranean area to Europe, including the northern German City States. As a result, a pound, 16 ounces of silver, or 7200 grains, became a commonly used measure in many regions. 90003 90002 While England also adopted this measure, a shortage of silver caused King Offa to reduce the measurement of the pound to 5400 grains in order to use smaller coins. Eventually, when William the Conqueror became King of England, he retained the 5400-grain pound for minting coins, but reverted to the 7200-grain pound for other purposes.90003 90002 Though many countries used the pound from that point onward, including England (the British pound sterling, or GBP was equal to one pound-weight of silver in King Offa’s time), the avoirdupois weight system was adopted during the reign of Queen Elizabeth in the 16th century. It was a system based on the weight of coal, and its name was derived from the French phrase «avoir de pois» (goods of weight or property). The avoirdupois was equivalent to 7,000 grains, 256 drams of 27.344 grains each, or 16 ounces of 437 ½ grains each.Since 1959 the avoirdupois pound has been officially defined in most English-speaking countries as 0.45359237 kilograms. 90003 90002 Different systems of measurement also developed over time in Asian countries. For example, in ancient India, a measure of weight called the «Satamana» was used, and was equal to the weight of 100 gunja berries. In China, the first emperor Shi Huang Di created a system of weights and measures in the third century BCE (before Common Era). The measurement of weight was based on the shi, which was equivalent to approximately 132 pounds.The Chi and Zhang were units of length equivalent to approximately 25 centimeters (9.8 inches) and 3 meters (9.8 feet) respectively. The Chinese also developed a means to ensure accuracy through use of a special size of bowl used for measurements that also made a specific sound when struck — if the sound was off pitch, the measurement was not accurate. 90003 90005 Brief History of the Metric System 90006 90002 In 1668, John Wilkins proposed a decimal system in which length, area, volume, and mass were linked to each other based on a pendulum that had a beat of one second as a base unit of length.In 1 670, Gabriel Mouton proposed a decimal system that was instead based on the circumference of the earth, an idea supported by other prominent scientists of the time such as Jean Picard and Christiaan Huygens, but that did not take hold for approximately another 100 years. 90003 90002 By the mid-eighteenth century, it was clear to nations who traded and exchanged scientific ideas that standardization of weights and measures was necessary. In 1790, Charles Maurice de Talleyrand-Perigord, the Prince of Talleyrand, approached the British (represented by John Riggs-Miller) and the Americans (represented by Thomas Jefferson) with proposals to define a common standard of length based on the length of a pendulum.In that same year, Thomas Jefferson, presented the «Plan for Establishing Uniformity in the Coinage, Weights, and Measures of the United States,» which advocated for a decimal system in which units were related to each other by powers of ten. A committee that was formed in France comprised of some of the most prominent scientists of the day came to a similar conclusion, and also proposed a decimal system for all weights and measures. Although Congress considered Jefferson’s report, it was not adopted.In Great Britain, John Riggs-Miller lost his British Parliamentary seat in the 1790 election. As such, the measurement system was only implemented in France, and in тисячі сімсот дев’яносто п’ять, the metric system was formally defined in French law. It was not until тисяча сімсот дев’яносто дев’ять however that the metric system was officially adopted in France, though it was still not universally observed across the country. 90003 90002 Spread of the metric system did not occur quickly, and areas that were annexed by France during Napoleon’s reign were the first to adopt the metric system.By 1875, two thirds of the European population, and nearly half the world’s population had adopted the metric system. By 1920 році, the percentage of the world’s population using the imperial system or the US customary system was ~ 22%, with 25% using mainly the metric system, and 53% using neither. 90003 90002 The International System of Units, currently the most widely used system of measurement, was published in 1960. It has been adopted by all developed countries except for the United States, though as previously mentioned, it is used in science, as well as heavily in the military, even in the US.90003 .90000 Conversion of fractional numbers between numeral systems 90001 90002 After I’ve made several calculators for numeral systems conversion (from the simplest one to more advanced: Conversion of decimal number to other notations, Conversion from decimal numeral system, Conversion between any bases — users often asked me, what should we do about fractional numbers, how to convert them? So, I decided to make another calculator, which can also convert fractional numbers between different numeral systems.90003 90002 As usual, I’ve placed some theory below the calculator 90005 90003 90007 90008 Conversion of fractional numbers between numeral systems 90009 90002 Input numeral system base 90003 90002 Target numeral system base 90003 Calculation precision 90002 Digits after the decimal point: 8 90003 90002 Source number (decimal) 90003 90002 90003 90002 Target number (decimal) 90003 90002 90003 90002 Conversion error (decimal) 90003 90002 90003 90002 Maximum conversion error possible (decimal) 90003 90002 90003 90002 90033 save 90034 Save 90033 extension 90034 Widget 90003 90002 So, I used to think that conversion of fractional numbers is difficult question, but it turns to be quite easy to understand.All we need to remember is that we deal with positional numeral system. 90003 90002 Let me show it on example. Take a look at decimal number 6.125. You can write it like this: 90003 90002 90003 90002 Easy to follow, is not it? But it is the same thing for any other positional numeral system. Let’s take, for example, infamous binary system, and fractional binary number 110.001. You can write it like this: 90003 90002 90003 90002 Yes, I’ve made it up. Binary 110.001 is decimal 6.125. Should not that easy? 90003 90002 But, there is one caveat.Since we have fractions, and the denominators are different, we can not always keep the same precision with different numeral systems. 90003 90002 Again, let me show it on example. Take a look at decimal number 0.8 90003 90002. 90003 90002 Everything is nice … for decimal numeral system. But for binary numeral system we have a problems. Look at this 90003 90002 90003 90002 We can go on, but even now we can see that decimal 0.8 is binary 0.11001100 … (and many digits). In fact, it is periodic number with period 1100, so we will not find the exact number of binary digits to write 0.8 precisely. It is 1100 all the way down. 90003 90002 That’s why conversion of fractional numbers often gives us conversion error. The error depends on number of digits after point which we decide to use. For example, let’s convert decimal 0.8 to binary and use 6 digits after the point. We will get 0.110011. But it is not decimal 0.8, in fact, it is decimal 0.796875, the difference is 0.003125. And this is our error during conversion decimal 0.8 to binary with 6 digits after the point. 90003 90002 The value of rightmost digit is called 90065 resolution 90066 or 90065 precision 90066, and defines the smallest possible nonzero number which can be written using this number of digits.For our example it is. And maximum possible conversion error in that case is one-half of it, or 0.0078125. Note that our conversion error for 0.8 is not that bad comparing to maximum possible error. 90003 90002 That’s all. 90003.90000 Online Conversion — Convert just about anything to anything else 90001 90002 All Conversion Pages and Categories 90003 90002 Acceleration Many different acceleration constants. g-unit, meter / square second, more … 90003 90002 Angles Gradients, Radians, Degrees, Minutes, Seconds, Points, More … 90003 90002 Area Square centimeter, Square meter, Square inch, Square foot, Square mile, Square Kilometer, Acres, Circles, More… 90003 90002 Astronomical Astronomical unit, light-years, parsecs, More … 90003 90002 Clothing Convert clothing sizes between many different countries. 90003 90002 Computers and Electronics Various conversions and calculators related to computers and electronics. 90003 90002 Cooking Various cooking volume conversions, including Drop, Dash, Pinch, Teaspoons, Tablespoons, Cups, etc. Plus other cooking conversions such as butter weight, and gas mark temperatures.90003 90002 Date / Time Several different converters and calculators related to dates and times. 90003 90002 Density kg / cubic meter, lbm / cubic foot, lbm / gallon, aluminum, copper, gold, water, More … 90003 90002 Energy Joules, Btu, calories, electronvolt, erg, watt hour, therm, toe, tce, More … 90003 90002 Finance Several calculators and conversions related to finance 90003 90002 Flow Rate Many different flowrate conversions.Includes separate pages for mass based, volume based, and mole based flowrates. 90003 90002 Force Dyne, gram-force, poundals, newtons, pounds, kgm-force, More … 90003 90002 Frequency Hertz, cycles per second, revolutions per second, degrees per second, radians per second, many more … 90003 90002 Fun Stuff Several fun and interesting calculators and conversions 90003 90002 Length / Distance Millimeters, Centimeters, Inches, Feet, Yards, Meters, Kilometers, Miles, Mils, Rods, Fathoms, Nautical Miles, More… 90003 90002 Light Conversion calculators for illuminance and luminance. 90003 90002 Mapping Many calculators and converters related to mapping and navigation. 90003 90002 Miscellaneous Several calculators and conversions that did not fit any other category 90003 90002 Numbers Number conversions and information.

This calculator converts a number word phrase such as 2.75 million into its numerical equivalent. The number word phrase 2.75 million converts to numbers in standard notation as 2,750,000 and also scientific notation as 2.75 x 10 90005 6 90006. 90007 90008 What is Standard Notation? 90003 90004 Standard notation of a number is when a number is written with only number digits.This is the typical way to write numbers since words are not used in standard number notation. You may see standard notation numbers with thousand separators (commas) and decimal indicators (periods), but not with words like «trillions» or «hundredths.» 90007 90008 Why Use Number Word Notation? 90003 90004 Number and word notation is usually used when exact figures are not required but the magnitiude of a value is important in explaining a point or story. 90007 90016 Example number word notation: The U.S. national debt is more than 16.76 trillion dollars. 90017 90004 Converting from number word form to standard number notation: 90019 16.76 trillion = 16.76 x 10 90005 12 90006 = 16,760,000,000,000 90019 If you need to say the number 16,760,000,000,000 you would say, «sixteen trillion, seven hundred sixty billion.» 90007 90016 Example number word notation: The fastest CPU operation executes in less than 4 millionths of a second.90017 90004 Converting from number word form to standard number notation: 90019 4 millionths = 4 x 10 90005 -6 90006 = 0.000004 90019 If you need to say the number 0.000004 you would simply say «four millionths.» 90007 90016 Example number word notation: What is 2 millionths of a billionth of a second? 90017 90004 Converting from number word form: 90019 2 millionths = 2 x 10 90005 -6 90006 90019 1 billionth = 1 x 10 90005 -9 90006 90007 90004 2 Millionths of 1 Billionth 90019 = 2 x 10 90005 -6 90006 * 1 x 10 90005 -9 90006 90019 = (2 * 1) x 10 90005 (-6 + -9) 90006 = 2 x 10 90005 -15 90006 seconds.90007 90008 What is Standard Form? 90003 90004 «Standard form» is typically used in England and Great Britain to refer to the scientific number notation that the US calls «scientific notation.» Standard form and scientific notation are essentially the same way to refer to the notation used to represent very large or very small numbers such as 4.959 × 10 90005 12 90006 or 1.66 × 10 90005 -24 90006. 90007 90008 Related Calculators 90003 90004 Use the Decimal and Integer Calculator to do common math or math on very large or very small numbers using E notation inputs.90007 90004 To convert numbers to words see our Numbers to Words Converter. 90007 .
