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.

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

The following example uses the Abs function to compute the absolute value of a number:

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