Math.Abs Method (SByte)

Returns the absolute value of an 8-bit signed integer.

This method is not CLS-compliant.  

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

[CLSCompliantAttribute(false)] 
public static sbyte Abs (
	sbyte value
)
/** @attribute CLSCompliantAttribute(false) */ 
public static SByte Abs (
	SByte value
)
CLSCompliantAttribute(false) 
public static function Abs (
	value : sbyte
) : sbyte
Not applicable.

Parameters

value

A number in the range MinValue < valueMaxValue.

Return Value

An 8-bit signed integer, x, such that 0 x MaxValue.

Exception typeCondition

OverflowException

value equals MinValue.

The following example demonstrates how to use the Abs method to display the absolute values of a list of variables.

// This example demonstrates Math.Abs()
using System;

class Sample 
{
    public static void Main()
    {
    sbyte    sb1 = -16, sb2 = 16;
    short    sh1 = -15, sh2 = 15;
    int      in1 = -14, in2 = 14;
    long     lg1 = -13, lg2 = 13;
    float    fl1 = -12.0f, fl2 = 12.0f;
    double   db1 = -11.1, db2 = 11.1;
    Decimal  de1 = -10.0m, de2 = 10.0m;

    Console.WriteLine();
    Console.WriteLine("SByte:   1) {0,-5} 2) {1,-5}", Math.Abs(sb1), Math.Abs(sb2));
    Console.WriteLine("Int16:   1) {0,-5} 2) {1,-5}", Math.Abs(sh1), Math.Abs(sh2));
    Console.WriteLine("Int32:   1) {0,-5} 2) {1,-5}", Math.Abs(in1), Math.Abs(in2));
    Console.WriteLine("Int64:   1) {0,-5} 2) {1,-5}", Math.Abs(lg1), Math.Abs(lg2));
    Console.WriteLine("Single:  1) {0,-5} 2) {1,-5}", Math.Abs(fl1), Math.Abs(fl2));
    Console.WriteLine("Double:  1) {0,-5} 2) {1,-5}", Math.Abs(db1), Math.Abs(db2));
    Console.WriteLine("Decimal: 1) {0,-5} 2) {1,-5}", Math.Abs(de1), Math.Abs(de2));
    }
}
