How to format a decimal without trailing zeros

Question

I\'ve just learned that a decimal somehow remembers how much trailaing zero\'s were needed to store a number. With other words: it remembers the size of the fraction.

There are several ways to do it, but since you are converting to a String object anyway, I suppose you could try something like this:

myDecimalVariable.ToString("G29");

or, using your code above, assuming 123.00M is your decimal:

123.00M.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.
