FLOOR function

This article describes the formula syntax and usage of the FLOORfunction in Microsoft Excel.

Description

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

Syntax

FLOOR(number, significance)

The FLOOR function syntax has the following arguments:

• Number    Required. The numeric value you want to round.

• Significance    Required. The multiple to which you want to round.

Remarks

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

• If number is positive and significance is negative, FLOOR returns the #NUM! error value.

• If the sign of number is positive, a value is rounded down and adjusted toward zero. If the sign of number is negative, a value is rounded down and adjusted away from zero. If number is an exact multiple of significance, no rounding occurs.
