The absolute value of a number is its unsigned magnitude. For example, ABS(-1) and ABS(1) both return 1.
Note: Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box.
This example uses the Abs function to compute the absolute value of a number.
MyNumber = Abs(50.3) ' Returns 50.3.
MyNumber = Abs(-50.3) ' Returns 50.3.
