``` ABS()
Return the absolute value of a numeric expression
------------------------------------------------------------------------------
Syntax

ABS(<nExp>) --> nPositive

Arguments

<nExp> is the numeric expression to be evaluated.

Returns

ABS() returns a number representing the absolute value of its argument.
The return value is a positive number or zero.

Description

ABS() is a numeric function that determines the magnitude of a numeric
value independent of its sign.  It lets you, for example, obtain the
difference between two numbers as a positive value without knowing in
advance which of the two is larger.

As a formalism, ABS(x) is defined in terms of its argument, x, as
follows: if x >= 0, ABS(x) returns x; otherwise, ABS(x) returns the
negation of x.

Examples

.  These examples show typical results from ABS():

nNum1 := 100
nNum2 := 150
? nNum1 - nNum2                  // Result: -50
? ABS(nNum1 - nNum2)             // Result: 50
? ABS(nNum2 - nNum1)             // Result: 50
? ABS(-12)                       // Result: 12
? ABS(0)                         // Result: 0
