Computer number format - Simple English Wikipedia, the free encyclopedia

A computer number format is the way that computers and calculators represent numbers. Most computers use a system of binary which is composed of ones and zeros.

Other systems in use are the octal (0,1-7) or the hexadecimal (0,1-9,A,B,C,D,E,F) systems.

So we can use codes, which the computer understands only, as well as other number systems.
