Calculate token cost from a given price and delimiter

Mathematics
Algorithms
Logic
Numbers

Removed duplicate code and multiple executions of fmod by calculating it before all the places where it's needed, reducing probability of copy/paste error and slightly improving performance.
Also added a space before every left bracket, for readability (personal preference).
