Hi,
If you use the default .ToString(string format) you don't have to do the rounding yourself - it's built in. So an extension method like this should do what you need:

public static string ToString(this Decimal myValue, int strLength, byte decimalPos, string justify = "R", bool zeroFill = true, bool showDecimal = true)
        {
            char padChar = zeroFill ? '0' : ' ';
            string s = myValue.ToString("." + new string('0', decimalPos));  //This rounds...
            if (!showDecimal) { s = s.Replace(".", ""); }
            string padding = new string(padChar, strLength - s.Length);
            return (justify == "R") ? padding + s : s + padding;
        }

Then, as examples:

string s = 1234.56M.ToString(10, 2, "R");
 s = 1234.56M.ToString(10, 4, "",false);
 s = 1234.56M.ToString(10, 2, "R",true,false);
 s = 134.5645676M.ToString(10, 4, "");
 s = .5645676M.ToString(10, 4, "");
 s = 1.99999M.ToString(10, 4,"",false);

The order of the default parameters might be improved tho....

>>I think you probably need to do something before you replace the decimal point. Check that the number of positions past the decimal point equals your decimalPos value, pad with zeroes if it doesn't, then go ahead and remove the decimal point. I think that should solve your problem.
