FLOOR
Rounds number down, toward zero, to the nearest multiple of significance.
Syntax
FLOOR(number,significance)
Number is the numeric value you want to round.
Significance is the multiple to which you want to round.
Remarks
- If either argument is nonnumeric, FLOOR returns the #VALUE! error value.
- If number and significance have different signs, FLOOR returns the #NUM! error value.
- Regardless of the sign of number, a value is rounded down when adjusted away from zero. If number is an exact multiple of significance, no rounding occurs.

| Formula | Description (Result) |
|---|---|
| =FLOOR(2.5, 1) | Rounds 2.5 down to nearest multiple of 1 (2) |
| =FLOOR(-2.5, -2) | Rounds -2.5 down to nearest multiple of -2 (-2) |
| =FLOOR(-2.5, 2) | Returns an error, because -2.5 and 2 have different signs (#NUM!) |
| =FLOOR(1.5, 0.1) | Rounds 1.5 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) |
