ABS Function

What is the syntax for the Abs function and how does it
work? This function was included in an equation that was
recommended to solve a problem that I had, but I do not
understand the function.

From the Help file:

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

Syntax

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.

Remarks

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