string test = (1.23M * 100M).ToString("0");
//prints 123.

//prints 123.45.
string test3 = 123.450M.ToString().Trim('0');

myDecimalVariable.ToString("G29");

Here is the explanation of how that concise example works:

The G format with a number means to format that many significant digits. Because 29 is the most significant digits that a Decimal can have, this will effectively truncate the trailing zeros without rounding.
