Math

C# provides a System.Math class, that offers many powerful and useful fields and methods, which allow you to perform various mathematical operations and tasks on numbers.

Math is a very important aspect of programming, and almost all programs use Math to some degree. This System.Math class makes it much easier for your program to perform more advanced mathematical tasks by providing you with well written canned functions (so that you do not have to write your own math functions).

Fields

System.Math class provides the following ready to use fields:

Methods

System.Math class provides the following ready to use methods. Depending on the method, the supplied number value for n might be a decimal, double-precision floating-point, or integer number:

The following is a code example showing how to use the System.Math class to round a decimal number to the nearest integer value:

using System;
namespace MyApp
{
  class MainProgram
  {
    static void Main(string[] args)
    {
      Console.WriteLine(Math.Round(9.968352));
    }
  }
}

The output is: 10

Since the Math.Round() method has an overload for allowing you to specify the decimal number to round a decimal number to, the following is a code example showing how to use the System.Math class to round a decimal number to two decimal places:

using System;
namespace MyApp
{
  class MainProgram
  {
    static void Main(string[] args)
    {
      Console.WriteLine(Math.Round(9.968352, 2));
    }
  }
}

The output is: 9.97
