This article describes the formula syntax and usage of the FLOOR function.
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.
Example
| Formula | Description | Result |
| =FLOOR(3.7,2) | Rounds 3.7 down to nearest multiple of 2. | 2 |
| =FLOOR(-2.5,-2) | Rounds -2.5 down to nearest multiple of -2. | -2 |
| =FLOOR(2.5,-2) | Returns an error value, because 2.5 and -2 have different signs. | #NUM! |
| =FLOOR(1.58,0.1) | Rounds 1.58 down to the nearest multiple of 0.1. | 1.5 |
| =FLOOR(0.234,0.01) | Rounds 0.234 down to the nearest multiple of 0.01. | 0.23 |
