I did a coding assignment one of these days that needed me to round a given price to the nearest even cent. Though the requirement was a bit odd, it became interesting when I realized that the built-in rounding methods in .Net were not sufficient. 10.346 has to round to 10.34 10.356 has to round to 10.36 I wrote the following method to implement this: public static decimal RoundToEvenCents( decimal sourceNumber) { var tempNumber = sourceNumber * 100; var lowerValue = Math.Floor(tempNumber); var upperValue = Math.Ceiling(tempNumber); var evenValue = (lowerValue % 2 == 0) ? lowerValue : upperValue; return evenValue / 100; } Though I am not sure if this is a valid business requirement, putting it here just in case somebody needs it.
