# decimal

Refers to numbers in base 10 (the numbers we use in everyday life). For example, the following are decimal numbers:9

100345000

Note that a decimal number is not necessarily a number with a decimal point in it. Numbers with decimal points (that is, numbers with a fractional part) are called *fixed-point* or *floating-point numbers*.

In addition to the decimal format, computer data is often represented in binary, octal, and hexadecimal formats.
