How many decimal bases are there? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The base of the decimal system is 10, which is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; all numbers are represented by 10 basic symbols, full decimal one, and the same symbol represents different values in different positions, so the position of the symbol is very important.

Decimal system

A method of counting. It is characterized by the fact that every decimal, that is, one digit forward when ten is over. For example, if a person reaches ten, add one out of ten; a hundred places over ten, add one out of a thousand.

When counting according to the "every decimal one" rule, every ten identical units form a higher unit adjacent to it. this method of counting is called decimal counting, or decimal for short. Its writing principle is the position principle.

Decimal number

The decimal number is made up of a 10-based number system, which is made up of ten basic numbers: 0, 4, 5, 6, 7, 8, 9. The decimal system, whose English name is Decimal System, comes from the Greek Decem, which means ten. Decimal counting was invented by Hindus 1500 years ago and passed down from Arabs to the 11th century.

Principle of use

The decimal system is based on the two principles of bit and decimal, that is, all numbers are represented by 10 basic symbols, full decimal one, and the same symbol represents different values in different positions, so the position of the symbol is very important.

The basic symbol is ten digits from 0 to 9.

To represent 10 times the ten numbers, move the numbers one bit to the right and fill the vacancy with 0, that is, 10, 10, 20, 30, 10, 10, 10, 5, 5, 5, 5, 5, 5, 5, 5, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 6, 4, 6, 4, 4, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6,

To represent 10 times of these ten numbers, continue to move the position of the number to the left, that is, 100, 200, 200, 300 and so on.

To represent the position of a number 1Compact 10, move the position of this number to the right and fill in the vacancy with 0 if necessary: 1Compact 10 bits 0.1jue 1Accord 100 for 0.01jue 1Accord 1000 is 0.001.
