ozzy 48a9837bef feat(eval): add rounding functions 
added:
- `round(num, dec)` -> rounds `num` to `dec` amount of decimal places with `RoundingStrategy::MidpointAwayFromZero`
- `floor(num)` -> floors `num` to the nearest integer
- `ceil(num)` -> ceils `num` to the nearest integer
fixed:
- use proper function types instead of function pointers for the util functions in the builtin function registry
