C#中如何开根号

Answer 1

c#中使用开平方函数
line=System.Math.Sqrt((ending.x-starting.x)*(ending.x-starting.x)+(ending.y-starting.y)*(ending.y-starting.y));
具体方式：
Console.WriteLine(Math.Sqrt(2.0)); //1.4142135623731
Console.WriteLine(Math.Pow(2, 2)); //4
Console.WriteLine(Math.Pow(9, 0.5)); //3
Console.WriteLine(Math.Pow(125, (1.0/3.0))); //5
