The following example demonstrates how the rounding functions work together. These functions include the following:
FLOOR- largest integer that is not greater than the input value. See FLOOR Function.CEILING- smallest integer that is not less than the input value. See CEILING Function.ROUND- nearest integer to the input value. See ROUND Function.MOD- remainder integer when input1 is divided by input2. See Numeric Operators.

| rowNum | X |
|---|---|
| 1 | -2.5 |
| 2 | -1.2 |
| 3 | 0 |
| 4 | 1 |
| 5 | 1.5 |
| 6 | 2.5 |
| 7 | 3.9 |
| 8 | 4 |
| 9 | 4.1 |
| 10 | 11 |
Transform:
derive type: single value: FLOOR (X) as: 'floorX'
derive type: single value: CEILING (X) as: 'ceilingX'
derive type: single value: ROUND (X) as: 'roundX'
derive type: single value: (X % 2) as: 'modX'
Results:
| rowNum | X | modX | roundX | ceilingX | floorX |
|---|---|---|---|---|---|
| 1 | -2.5 | -2 | -2 | -3 | |
| 2 | -1.2 | -1 | -1 | -2 | |
