Update mathematical functions (#675)

Browse Source 
Document the existing `ROUND`, `CEIL`, and `FLOOR` functions
Also update the trig function docs for searchability

Implement `POW` and `LOG`
Addresses part of #675

Implement ** for integer exponents
** has higher precedence than -, like Python, so -3**4 == -(3**4) == 81
