# Rounding functions



Use rounding functions to adjust numeric values to specific boundaries or intervals. These functions are essential for data binning, time-series aggregation, and converting continuous values to discrete buckets.

| Function                                                       | Description                                                                    |
| -------------------------------------------------------------- | ------------------------------------------------------------------------------ |
| [ceiling](/apl/scalar-functions/rounding-functions/ceiling)    | Rounds a number up to the smallest integer greater than or equal to the input. |
| [bin](/apl/scalar-functions/rounding-functions/bin)            | Rounds values down to an integer multiple of a specified bin size.             |
| [bin\_auto](/apl/scalar-functions/rounding-functions/bin-auto) | Rounds datetime values down to a fixed-size bin with automatic size selection. |
| [floor](/apl/scalar-functions/rounding-functions/floor)        | Rounds a number down to the largest integer less than or equal to the input.   |
