Absfunction

Calculates the absolute value of a number

Syntax

Declare Function Abs ( ByVal number As Integer ) As Integer

Declare Function Abs ( ByVal number As UInteger ) As UInteger

Declare Function Abs ( ByVal number As Double ) As Double

Parameters

Return value

The absolute value of number.

Description

The absolute value of a number is its positive magnitude. If a number is negative, its value will be negated and the positive result returned. For example, Abs(-1) and Abs(1) both return 1. The required number argument can be any valid numeric expression.
Unsigned numbers will be treated as if they were signed, i.e. if the highest bit is set the number will be treated as negative, and its value negated.
The value returned will be greater than or equal to 0, with the exception of signed integers containing the lowest possible negative value that can be stored in its type, in which case negating it will overflow the result.

The Abs unary Operator can be overloaded with user defined types.
