  • As long as the number and specified significance have the same sign, then FLOOR rounds TOWARDS zero to the nearest multiple of significance.

  • If either argument is nonnumeric, FLOOR returns the #VALUE! error value.

  • In Excel 2010 and Excel 2013, Excel allows positive and negative multiples of significance with negative numbers. In those cases, if the significance is positive FLOOR rounds away from zero. Otherwise,if significance is negative FLOOR rounds towards zero.

  • For positive numbers with negative multiples of significance, Excel 2010 and Excel 2013 returns the #NUM! error value.

  • If number is an exact multiple of significance, no rounding occurs.
