C# Math Abs(Double)

Description

Math Abs(Double) returns the absolute value of a double-precision floating-point number.

Syntax

Math.Abs(Double) has the following syntax.

public static double Abs(
  double value
)

Parameters

Math.Abs(Double) has the following parameters.

• value - A number that is greater than or equal to Double.MinValue, but less than or equal to Double.MaxValue.

Returns

Math.Abs(Double) method returns A double-precision floating-point number, x, such that 0 d x d Double.MaxValue.

Example

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

/* w  w  w.  j  a va 2s. co m*/
using System;

public class Example
{
   public static void Main()
   {
      double[] doubles = { Double.MaxValue, 16.354e-17, 15.123456, 0, 
                           -19.012345, -15.058e18, Double.MinValue };
      foreach (double value in doubles)
         Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value));
   }
}

The code above generates the following result.
