Math.Abs Method (Int32)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Returns the absolute value of a 32-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Int32
A number that is greater than Int32.MinValue, but less than or equal to Int32.MaxValue.
| Exception | Condition |
|---|---|
| OverflowException | 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 Math.Abs(Int32) method to get the absolute values of several Int32 values.
int[] values = { Int32.MaxValue, 16921, 0, -804128, Int32.MinValue }; foreach (int value in values) { try { outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) + "\n"; } catch (OverflowException) { outputBlock.Text += String.Format("Unable to calculate the absolute value of {0}.", value) + "\n"; } } // 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.
