WorksheetFunction.Floor method (Excel)

  • Article

Rounds number down, toward zero, to the nearest multiple of significance.

Important

This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. This function is still available for compatibility with earlier versions of Excel. However, if backward compatibility is not required, you should consider using the new functions from now on, because they more accurately describe their functionality.

For more information about the new function, see the Floor_Precise method.

Syntax

expression.Floor (Arg1, Arg2)

expression A variable that represents a WorksheetFunction object.

Parameters

Name Required/Optional Data type Description
Arg1 Required Double Number - the numeric value that you want to round.
Arg2 Required Double Significance - the multiple to which you want to round.

Return value

Double

Remarks

As long as the number and specified significance have the same sign, Floor rounds towards zero to the nearest multiple of significance.

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

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 returns the #NUM! error value.

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