How do you use the FLOOR function?

Considerations when using the FLOOR function

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

If number and significance have different signs, FLOOR returns the **#NUM!**error value.

Regardless of the sign of the number, a value is rounded down when adjusted away from zero. If the number is an exact multiple of significance, no rounding occurs.
