=== Math Functions
|
|
|
|
All math and trigonometric functions require their input (where applicable)
|
|
to be numeric.
|
|
|
|
==== Generic
|
|
|
|
* `ABS`
|
|
|
|
https://en.wikipedia.org/wiki/Absolute_value[Absolute value], returns \[same type as input]
|
|
|
|
["source","sql",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{sql-specs}/math.sql-spec[abs]
|
|
--------------------------------------------------
|
|
|
|
* `CBRT`
|
|
|
|
https://en.wikipedia.org/wiki/Cube_root[Cube root], returns `double`
|
|
|
|
// TODO make the example in the tests presentable
|
|
|
|
* `CEIL`
|
|
|
|
https://en.wikipedia.org/wiki/Floor_and_ceiling_functions[Ceiling], returns `double`
|
|
|
|
* `CEILING`
|
|
|
|
Same as `CEIL`
|
|
|
|
// TODO make the example in the tests presentable
|
|
|
|
* `E`
|
|
|
|
https://en.wikipedia.org/wiki/E_%28mathematical_constant%29[Euler's number], returns `2.7182818284590452354`
|
|
|
|
|
|
* https://en.wikipedia.org/wiki/Rounding#Round_half_up[Round] (`ROUND`)
|
|
|
|
// TODO make the example in the tests presentable
|
|
|
|
NOTE: This rounds "half up" meaning that `ROUND(-1.5)` results in `-1`.
