Ok, I broke this abstraction out a bit and made it easier to add
non-single-arg functions (a la POW, which is a separate PR by
@simonellistonball ). I also went ahead and added `ROUND` and `EXP`. I looked
through the remainder of the math functions and honestly, I didn't see a strong
reason to include any of the rest of them immediately. I'd RATHER them come in
via separate PRs with some justification of use.

> At the moment the math functions are woefully incomplete.
> We should add at least the ones difficult or impossible to reconstruct using

> * log10
> * log2
> * ln
> * sqrt
> * ceil
> * floor
> * sin
