Math.Abs() Method in C#

The Math.Abs() method in C# is used to return the absolute value of a specified number in C#. This specified number can be decimal, double, 16-bit signed integer, etc.

Example

Let us now see an example to implement the Math.abs() method to return the absolute value of double number −

using System;
class Demo {
   public static void Main(){
      Double val1 = 30.40;
      Double val2 = Double.MinValue;
      Double val3 = Double.MaxValue;
      Console.WriteLine("Absolute value of {0} : {1}", val1, Math.Abs(val1));
      Console.WriteLine("Absolute value of {0} : {1}", val2, Math.Abs(val2));
      Console.WriteLine("Absolute value of {0} : {1}", val3, Math.Abs(val3));
   }
}

Output

This will produce the following output −

Absolute value of 30.4 : 30.4
Absolute value of -1.79769313486232E+308 : 1.79769313486232E+308
Absolute value of 1.79769313486232E+308 : 1.79769313486232E+308

Example

Let us now see another example to implement the Math.abs() method to return the absolute value of 16-bit signed integer −

using System;
class Demo {
   public static void Main(){
      short val1 = -300;
      short val2 = Int16.MaxValue;
      short val3 = 0;
      Console.WriteLine("Absolute value of {0} : {1}", val1, Math.Abs(val1));
      Console.WriteLine("Absolute value of {0} : {1}" val2, Math.Abs(val2));
      Console.WriteLine("Absolute value of {0} : {1}", val3, Math.Abs(val3));
   }
}

Output

This will produce the following output −

Absolute value of -300 : 300
Absolute value of 32767 : 32767
Absolute value of 0 : 0
