Syntax:

Abs(number)

The number argument can be any valid numeric expression. If number contains Null, Null is returned; if it is an uninitialized variable, zero is returned.

Remarks

The absolute value of a number is its unsigned magnitude. For example, Abs(-1) and Abs(1) both return 1.

Dim MyNumber
MyNumber = Abs(50.3) ' Returns 50.3
MyNumber = Abs(-50.3) ' Returns 50.3
