Floor() rounds down a number to the nearest multiple of the step shifted by the offset number.
Compare with the ceil function, which rounds input numbers up.
Syntax:
Floor(x[, step[, offset]])
Return data type: numeric
Arguments:
| Argument | Description |
|---|---|
| x | Input number. |
| step | Interval increment. The default value is 1. |
| offset |
Defines the base of the step interval. The default value is 0. |
Examples and results:
| Examples | Results |
|---|---|
|
Floor(2.4) |
Returns 2 In this example, the size of the step is 1 and the base of the step interval is 0. The intervals are ...0 <= x <1, 1 <= x < 2, 2<= x <3, 3<= x <4.... |
|
Floor(4.2) |
Returns 4 |
|
Floor(3.88 ,0.1) |
Returns 3.8 In this example, the size of the interval is 0.1 and the base of the interval is 0. The intervals are ... 3.7 <= x < 3.8, 3.8 <= x < 3.9, 3.9 <= x < 4.0... |
|
Floor(3.88 ,5) |
Returns 0 |
|
Floor(1.1 ,1) |
Returns 1 |
|
Floor(1.1 ,1,0.5) |
Returns 0.5 In this example, the size of the step is 1 and the offset is 0.5. It means that the base of the step interval is 0.5 and not 0. The intervals are ...0.5 <= x <1.5, 1.5 <= x < 2.5, 2.5<= x <3.5,... |
