An inductive definition of an integer is a number that is either zero or an integer plus or minus one. An integer is a number with no fractional part. If written as a fixed-point number, the part after the decimal (or other base) point will be zero.

A natural number is a non-negative integer.

integer

A whole number. In programming, sending the number 123.398 to an integer function would return 123. Unsigned integers (UINT) can only be positive and have a value from 0 to 255. Signed integers (INT) can be positive or negative, and their leftmost bit is the sign bit. As a result of one less binary digit in the number, the maximum value of each INT is cut in half (-128 to +127). See integer arithmetic and floating point.
