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.

Answer 1

just apply the Format specifier zero and will remove the trailing zeros:

string test = (1.23M * 100M).ToString("0");
//prints 123.
string test2 = 123.450M.ToString(".00");
//prints 123.45.
string test3 = 123.450M.ToString().Trim('0');
