Abs Function

Applies to: Office 2013 | VBA

Returns a value of the same type that is passed to it specifying the absolute value of a number.


Abs( number )

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


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

This example uses the Abs function to compute the absolute value of a number.

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