Do math functions of constant expressions get pre-calculated at compile time?

Question

I tend to use math functions of constant expressions for convinience and coherence (i.e log(x)/log(2) instead of log(x)/0.3...). Since these functi

Answer 1

This happens at runtime since the code for the function only becomes available during the linking step (which happens after the compile step).

To optimize the step, use a global variable which you initialize before you use it.
