MathF.Sqrt() Method in C# with Examples

In C#, MathF.Sqrt(Single) is a MathF class(present in system namespace) method which is used to calculate the square root of the specified Single or float data type value.

Syntax: public static float Sqrt (float x);
Here, x is the number whose square root is to be calculated and type of this parameter is System.Single.

Return Type: This method returns the square root of x. If x is equal to NaN, NegativeInfinity, or PositiveInfinity, that value is returned. The return type of this method is System.Single.



Below are the examples to illustrate the use of the above-discussed method:

class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // taking positive value
        float x = 78521F;
  
        // taking negative value
        float x1 = -7824F;
  
        // Input positive value
        // Output will be square
        // root of x
        Console.WriteLine(MathF.Sqrt(x));
  
        // Input negative value,
        // Output will be NaN
        Console.Write(MathF.Sqrt(x1));
    }
}
