Math.Abs Method (Int64)
[ 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 64-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Int64
A number that is greater than Int64.MinValue, but less than or equal to Int64.MaxValue.
| Exception | Condition |
|---|---|
| OverflowException | value equals Int64.MinValue. |
The absolute value of an Int64 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(Int64) method to get the absolute value of several Int64 values.
long[] values = { Int64.MaxValue, 109013, 0, -6871982, Int64.MinValue }; foreach (long 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(9223372036854775807) = 9223372036854775807 // Abs(109013) = 109013 // Abs(0) = 0 // Abs(-6871982) = 6871982 // Unable to calculate the absolute value of -9223372036854775808.
