The MathF.Sign() method in C# returns an integer specifying the sign of the number.SyntaxFollowing is the syntax −public static int Sign (float val);Above, Val is the floating-point number whose sign is to be calculated.The return value is 0 if Val is zero. It’s -1 if the value is less than zero and 1 if the value is greater than zero.ExampleLet us now see an example to implement the MathF.Sign() method −using System; public class Demo { public static void Main(){ float val1 = 10.23898f; float val2 = -20.878788f; Console.WriteLine("MathF.Sign(val1) = ...
