Abs Function

Return the absolute value of a numeric expression, regardless of its sign.

Namespace: XSharp.RT
Assembly: XSharp.RT (in XSharp.RT.dll) Version: 2.19

Syntax

Copy

 FUNCTION Abs(
	nValue AS USUAL
) AS USUAL

public static Usual Abs(
	Usual nValue
)

Request Example View Source

Parameters

nValue: Type: Usual
The numeric expression to evaluate.

Return Value

Type: Usual
A positive number or 0.

Remarks

Absolute value is the same as nValue if nValue is greater than or equal to 0.
It is the negation of nValue if nValue is less than 0.
Abs() lets you get the difference between the magnitude of
two numbers, where magnitude is the distance from the origin or zero.

Examples

These examples show typical results from Abs():

Copy

 1nNum1 := 100
 2nNum2 := 150
 3? nNum1 - nNum2                // -50
 4? ABS(nNum1 - nNum2)            //  50
 5? ABS(nNum2 - nNum1)            //  50
 6? ABS(-12)                    //  12
 7? ABS(0)                    //  0
 8nSouth := -5
 9nNorth := 4
10? ABS(nSouth) - ABS(nNorth)        // 1
11? ABS(nSouth) > ABS(nNorth)        // TRUE
12? nSouth > nNorth            // FALSE
