Trim Decimal Places

Question

Hi Everyone I was wondering if someone could help me. I am recieving prices from a XML steam and I am wondering how to strip off some decimal places. The price I get back looks like 12.5210125 and I only want to keep 2 decimal places. How can I strip off the extra decimal places so I get 12.52 Could I use a Trim of a Substring method? Thanks in advance. Jay

Mathematical aproach vs. string aproach: decimal result = decimal.Truncate( ValueToTruncate * 100 ) / 100;

Or you could make it easier for yourself. DataFromXMl = DataFromXml.SubString(0 DataFromXml.IndexOF(.) + 2); This returns a string beginning with the first char to a length 2 greater than the length of string at index of '.' Of course if you do want it in a decimal form you could do something like this decimal b = decimal.parse(DataFromXMl = DataFromXml.SubString(0 DataFromXml.IndexOF(.) + 2)); No point converting from one to the another just to convert back to a string!!!

Rounding is not the same as trimming. You could multiply by 100 cast to int and divide by 100.0.
