It seems that he wants to redefine how mathematics works.

double d = 9.5;<br />
      d = Math.Floor(d) + ((Math.Floor(d) + 1) - d) / 10;<br />

I simply want to count
how many decimals are in the string, unfortunately everything in regex seems to involve
replacing the decimals...and regex seems really heavy way of doing something that should
be simple.

Int32 decimalCount = text.Split('.')[1].Length

Int32 decimalCount = text.IndexOf('.') > -1 ? text.Split('.')[1].Length : 0;

[System.STAThreadAttribute]
static void Main(string[] args)
{
    int d ;
 
    args [ 0 ] = args [ 0 ].Trim( new char[] { '0' } ) ;
    d = args [ 0 ].IndexOf ( '.' ) ;
 
    if ( d >= 0 )
    {
        d = args [ 0 ].Length - d - 1 ;
    }
    else
    {
        d = 0 ;
    }
 
    System.Console.WriteLine ( d ) ;
}

int d ;

args [ 0 ] = args [ 0 ].Trim( new char[] { '0' } ) ;

System.Console.WriteLine
(
    ( d = args [ 0 ].IndexOf ( '.' ) ) == -1 ? 0 : args [ 0 ].Length - d - 1
) ;

int pos = text.IndexOf('.');
int decimalCount;
if (pos == -1) {
   decimalCount = 0;
} else {
   decimalCount = value.Length - pos - 1;
}

int pos = text.IndexOf('.');
int decimalCount = (pos == -1) ? 0 : value.Length - pos - 1;
