C# Example of Math.Sign() Method

The source code to demonstrate the use of Sign() method of Math class is given below. The given program is compiled and executed successfully.

using System;

class Sample {
  //Entry point of Program
  static public void Main() {
    int ret = 0;

    ret = Math.Sign(-52m);
    if (ret == 0)
      Console.WriteLine("Equal to zero");
    else if (ret == -1)
      Console.WriteLine("Less than zero");
    else
      Console.WriteLine("Greater than zero");

    ret = Math.Sign(52m);
    if (ret == 0)
      Console.WriteLine("Equal to zero");
    else if (ret == -1)
      Console.WriteLine("Less than zero");
    else
      Console.WriteLine("Greater than zero");
  }
}
