What Is Decimalisation?
600, 3/5, -7.99 ... Looking at these familiar numbers, have you thought too much? In fact, these are all decimals commonly used in the world, that is, 1. full ten, one full, twenty, two, and so on ... 2. according to the right, the first right is 10 ^ 0, the second one is 10 ^ 1 ... and so on, the Nth bit is 10 ^ (N-1), and the value of the number is equal to the value of each bit * the sum of the weights corresponding to the bit.
- Human arithmetic uses decimal, which may be related to humans having ten fingers.

- The "Epoque" records that people in the Shang Dynasty have learned to use the 13 words of one, two, three, four, five, six, seven, eight, nine, ten, one hundred, one thousand or ten thousand to write down any number less than 100,000. , But now the largest number that can be confirmed at that time was 30,000.

- Babylon's 60-carry system uses an upper, lower and lower wedge to represent 1, two parallel wedges to represent 2, three parallel wedges to represent 3, upper two wedges to lower two wedges to represent 4, upper three wedges to lower wedge to represent 5, and upper Three wedges, three wedges, six, four wedges, three wedges, seven, four wedges, four wedges, eight, and five wedges, four wedges, 9; one left, right and large wedges on behalf of 10, two wedges side by side Represents 20, three cross wedges side by side represents 30, and four cross wedges side by side represents 40.
- Chinese decimal weights and measures have a long history. A Zhou ruler in the 6th century BC was engraved with a tenth of an inch and a cent of a cent.
- Decimal. The English name is Decimal System. The decimal count was invented by Hindus 1500 years ago, and was passed down to the 11th century by Arabs.
- Decimal is based on the two principles of decimal and decimal, that is, all numbers are represented by 10 basic symbols, full decimal, and the same symbol has different values at different positions. The position of the symbol is very important. Basic symbols are 0 to 9 ten digits. To represent ten times these ten numbers, shift these numbers to the left by one, and fill in the spaces with 0, that is, 10, 20, 30, ..., 90; to represent ten times these ten numbers, continue Move the number to the left, that is, 100, 200, 300, ... To represent 1/10 of a number, shift the position of the number to the right, and add 0 spaces if necessary: 1/10 of 0.1, 1/100 is 0.01, and 1/1000 is 0.001. --Excerpted from "Statistics" Appendix 3 Mathematical Basics P205-6 [English] Tim Hannagan 2008.1

- Decimal notation is relative
- Binary number conversion
- Binary number to decimal number
- The basic method for converting binary numbers to decimal numbers is to first write the binary numbers as a weighted coefficient expansion and then sum them according to the decimal addition rule. This practice is called the "add by weight" method. Example 1105 converts the binary number 110.11 into a decimal number.
- Decimal number to binary number
- When converting a decimal number to a binary number, the integer and decimal parts are converted differently, so the integer part and decimal part of the decimal number are converted separately and then combined.
- 1. Decimal integers are converted to binary integers. Decimal integers are converted to binary integers using the "divide by 2 and remainder in reverse order" method. The specific method is: divide the decimal integer by 2 to get a quotient and the remainder; and then divide the quotient by 2 to get a quotient and the remainder. This is done until the quotient is zero, and then the remaining remainder is used as a binary number The low-order significant digits of the digits are used as the high-order significant digits of the binary number.
- 2. Decimal decimal to binary decimal
- Decimal decimals are converted to binary decimals using the "multiply by 2 round, order" method. The specific method is: multiply the decimal fraction by 2 to get the product. Take out the integer part of the product. Then multiply the remaining decimal part by 2 to get another product. Then take out the integer part of the product. The decimal part is zero, or until the required precision is reached.
- Then arrange the taken out integers in order. The integer taken first is taken as the significant significant digit of the binary fraction, and the integer taken later is taken as the significant significant digit. [3]
