The editor would like to share with you what the 10 digits in the decimal number are. I believe most people don't know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it!

In computer values, there are three concepts: number, cardinality, and bit weight that must be mastered.

Digital: different numeric symbols in a number system that represent the size of the basic value. There are 10 digits in the decimal system: 0, 1, 2, 3, 4, 5, 5, 6, 7, 8, 9.

Cardinality: the number of digits used in a value. The base of binary is 2 and the decimal is 10.

Bit weight: the size of the value represented by the 1 on a bit in a value. For example, the bit weight of decimal 345 3 is 100 3, the weight of 10 4 is 10, and the bit weight of 5 is 1

According to the weight, the first right is 10 ^ 0, and the second is 10 ^ 1. And so on, the N bit 10 ^ (Nmur1), the number of which is equal to the value of each bit * the sum of the weights corresponding to that bit.

Computers can only recognize binary numbers, but people are familiar with decimal numbers and are not used to using binary numbers. therefore, decimal numbers are often used when computers input and output data. The difference is that the decimal number here is represented by binary coding. A decimal number has ten digits, and a decimal number needs to be represented by a four-digit binary number, but it is still "every decimal number", so it is called a binary coded decimal number, or binary decimal number, or BCD (Binary coded Decimal) code for short.

The above is all the contents of the article "what are 10 digits in decimal numbers". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
