This example demonstrates Math Sign()

using System; class Sample  {     public static void Main()      {         byte     xByte1    = 0;             short    xShort1   = -2;         int      xInt1     = -3;         long     xLong1    = -4;         float    xSingle1  = 0.0f;         double   xDouble1  = 6.0;         Decimal  xDecimal1 = -7m;              sbyte    xSbyte1   = -101;              Console.WriteLine(Test(Math.Sign(xByte1)));         Console.WriteLine(Test(Math.Sign(xShort1)));         Console.WriteLine(Test(Math.Sign(xInt1)));         Console.WriteLine(Test(Math.Sign(xLong1)));         Console.WriteLine(Test(Math.Sign(xSingle1)));         Console.WriteLine(Test(Math.Sign(xDouble1)));         Console.WriteLine(Test(Math.Sign(xDecimal1)));         Console.WriteLine(Test(Math.Sign(xSbyte1)));     }     public static String Test(int compare)     {         if (compare == 0)             return "equal to";         else if (compare < 0)               return "less than";         else              return "greater than";     } }
