FLOOR Function (DAX)
Rounds a number down, toward zero, to the nearest multiple of significance.
|number||The numeric value you want to round.|
|significance||The multiple to which you want to round. The argumentsnumber and significance must either both be positive, or both be negative.|
A decimal number.
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.
