Math.Abs Method (Double)

Silverlight

Updated: September 2010

Returns the absolute value of a double-precision floating-point number.

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

[SecuritySafeCriticalAttribute]
public static double Abs(
	double value
)

Parameters

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

Return Value

Type: System.Double
A double-precision floating-point number, x, such that 0 ≤ x ≤ Double.MaxValue.

Remarks

The absolute value of a Double is its numeric value without its sign. For example, the absolute value of both 1.2e-03 and -1.2e03 is 1.2e03.

If value is equal to NegativeInfinity or PositiveInfinity, the return value is PositiveInfinity. If value is equal to NaN, the return value is NaN.

Examples

The following example uses the Math.Abs(Double) method to get the absolute value of several Double values.


double[] doubles = { Double.MaxValue, 16.354e-17, 15.098123, 0, 
                     -19.069713, -15.058e18, Double.MinValue };
foreach (double value in doubles)
   outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) + "\n";

// The example displays the following output:
//       Abs(1.79769313486232E+308) = 1.79769313486232E+308
//       Abs(1.6354E-16) = 1.6354E-16
//       Abs(15.098123) = 15.098123
//       Abs(0) = 0
//       Abs(-19.069713) = 19.069713
//       Abs(-1.5058E+19) = 1.5058E+19
//       Abs(-1.79769313486232E+308) = 1.79769313486232E+308
