Abs Method (Int32)

Math.Abs Method (Int32)

Returns the absolute value of a 32-bit signed integer.

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

public static int Abs(
	int value


Type: System.Int32
A number that is greater than Int32.MinValue, but less than or equal to Int32.MaxValue.

Return Value

Type: System.Int32
A 32-bit signed integer, x, such that 0 x Int32.MaxValue.


value equals Int32.MinValue.

The absolute value of an Int32 is its numeric value without its sign. For example, the absolute value of both 123 and -123 is 123.

The following example uses the Abs(Int32) method to get the absolute value of a number of Int32 values.

int[] values = { Int32.MaxValue, 16921, 0, -804128, Int32.MinValue };
foreach (int value in values)
   try {
      Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value));
   catch (OverflowException) {
      Console.WriteLine("Unable to calculate the absolute value of {0}.", 
// The example displays the following output:
//       Abs(2147483647) = 2147483647
//       Abs(16921) = 16921
//       Abs(0) = 0
//       Abs(-804128) = 804128
//       Unable to calculate the absolute value of -2147483648.
