C# Math

The C# Math class has many methods that allows you to perform mathematical tasks on numbers.

Math.Max(x,y)

The Math.Max(x,y) method can be used to find the highest value of x and y.

Math.Min(x,y)

The Math.Min(x,y) method can be used to find the lowest value of of x and y.

Math.Sqrt(x)

The Math.Sqrt(x) method returns the square root of x.

Math.Abs(x)

The Math.Abs(x) method returns the absolute (positive) value of x.

Math.Round()

Math.Round() rounds a number to the nearest whole number.

Examples

Max and Min

Finding maximum and minimum values.

using System;

class Program
{
  static void Main(string[] args)
  {
    Console.WriteLine(Math.Max(5, 10));
    Console.WriteLine(Math.Min(5, 10));
  }
}

Square Root

Calculating square root.

using System;

class Program
{
  static void Main(string[] args)
  {
    Console.WriteLine(Math.Sqrt(64));
  }
}

Absolute Value

Getting absolute value.

using System;

class Program
{
  static void Main(string[] args)
  {
    Console.WriteLine(Math.Abs(-4.7));
  }
}

Rounding

Rounding to nearest integer.

using System;

class Program
{
  static void Main(string[] args)
  {
    Console.WriteLine(Math.Round(9.99));
  }
}
