The Math Class
Round, sqrt, pow, and friends.
Meet the Math Class
The System.Math class provides ready-made mathematical functions and constants.
Its members are static, so you call them on the class itself, like Math.Sqrt(16), without creating an object.
double root = Math.Sqrt(16);
Console.WriteLine(root);Powers and Roots
Math.Pow(x, y) raises x to the power y, and Math.Sqrt(x) returns the square root.
Both return a double, even when the inputs are whole numbers.
Console.WriteLine(Math.Pow(2, 10));
Console.WriteLine(Math.Sqrt(144));
