Example

The following example demonstrates using the Math.Sqrt(double) method.

C# Example

using System; public class MathSqrtExample { public static void Main() { Double d1 = Math.Sqrt(16.0); Double d2 = Math.Sqrt(0.0); Double d3 = Math.Sqrt(-10.0); Console.WriteLine("Math.Sqrt(16.0) returns {0}", d1); Console.WriteLine("Math.Sqrt(0.0) returns {0}", d2); Console.WriteLine("Math.Sqrt(-10.0) returns {0}", d3); } }

The output is

Math.Sqrt(16.0) returns 4
Math.Sqrt(0.0) returns 0
Math.Sqrt(-10.0) returns NaN
