Is there a function or any other way to calculate in C the logarithm of base x, where x is an integer variable of my program?
C doesn’t provide functions to compute logarithms of any bases other than
eor10.So just use math:
If you’ll be doing the logarithms over the same base repeatedly, you can precompute
1/log(b).I wouldn’t rely on the compiler being able to do this optimization for you.
