## How does the FLOORfunction (DAX) work?

The FLOOR function (DAX) rounds a number down, toward zero, to the nearest multiple of significance.

## FLOOR Formula Syntax

FLOOR(
<number>, <significance>
)

## How do you use the FLOOR function?

The FLOOR function rounds a number down to a given multiple. FLOOR works like the MROUND function, which also rounds to a given multiple, but FLOOR always rounds down.

## 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.
