-* `map(x, in_min, in_max, out_min, out_max)`
-  Remaps the value `x` from its input range to an output range
-* `mapi(x, in_min, in_max, out_min, out_max)`
-  same as `map` but always returns an integer

 * `random(low, high=None)`
   Returns a random number between `0` and `low` - 1 if no `high` is provided, otherwise a value between `low` and `high` - 1
