Abs Method (Int32)

Math.Abs Method (Int32)

.NET Framework 4.6 and 4.5

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

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

Syntax

```public static int Abs(
int value
)
```

Parameters

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.

Exceptions

Exception Condition
OverflowException

value equals Int32.MinValue.

Remarks

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.

Examples

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

```using System;

public class Example
{
public static void Main()
{
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}.",
value);
}
}
}
}
// 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.
```
