find the square root of a number in csharp

To find the square root of a number in C#, you can use the Math.Sqrt method. This method takes a double as input and returns the square root of the number.

Here's an example usage:

main.cs
double number = 16.0;
double result = Math.Sqrt(number);
Console.WriteLine(result); // Output: 4.0
99 chars
4 lines

In this example, we first declare a double variable named number and assign it the value 16.0. Then, we use the Math.Sqrt method to calculate the square root of number and store the result in the result variable. Finally, we use the Console.WriteLine method to print the result to the console. The output will be 4.0.
