Returns the absolute value of a 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.
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:
Dim MyNumber MyNumber =
)' Returns 50.3. MyNumber =
)' Returns 50.3.
