Abs Function

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

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