Mathematical Functions in C#

The System.Math class in C# provides methods are properties to perform mathematical operations, trigonometric, logarithmic calculations, etc.

Some of its methods include −

For all the methods, refer MSDN

Let us see an example to get the absolute value −

Example

using System;

class Program {
   static void Main() {
      int val1 = 250;
      int val2 = -150;

      Console.WriteLine("Before...");
      Console.WriteLine(val1);
      Console.WriteLine(val2);

      int abs1 = Math.Abs(val1);
      int abs2 = Math.Abs(val2);

      Console.WriteLine("After...");
      Console.WriteLine(abs1);
      Console.WriteLine(abs2);
   }
}

Logarithmic and Trigonometric functions are also part of the System. Math class in C#. Trigonometric Functions in C# includes ACos, ASin, Sin, Cos, Tan, etc. It comes under the Math type of the System namespace.

The following is an example showing how to implement trigonometric functions in C# −

Example

using System;

class Program {
   static void Main() {
      Console.WriteLine(Math.Acos(0));
      Console.WriteLine(Math.Cos(2));

      Console.WriteLine(Math.Asin(0.2));
      Console.WriteLine(Math.Sin(2));
   }
}
