* CEILING.MATH was added in Excel 2013 to replace this function.
* This function is only available for backwards compatibility and should not be used.
* Positive decimal numbers with a positive significance are rounded up.
* Positive decimal numbers with a negative significance returns #NUM!
* Negative decimal numbers with a positive significance are rounded up.
* Negative decimal numbers with a negative significance are rounded down.
* If "significance" = 0 and "number" <> 0, then #DIV/0! is returned.
* If "significance" = 0 and "number" = 0, then zero is returned.
* There was also a FLOOR function that can round down positive numbers.
* This function has been available since Excel 1997.
