Thread: decimal to number if digits in different bases

Don't use log (or any other function out of math.h). [There is a suggestion above about "how to do it if you don't know much math" which would work]

But I doubt there's much point to that. Using -lm is fine unless you have a particularly quirky tutor... [Or the particular wording to your project says "do not use the math library" or some such].

A bit slow today, are we?

And the reason that gcc-mingw is "different" here is that it's not using glibc, but rather the MS C-library (msvcrt.dll), which has both math and standard library functions in one library, so there's no need to inform gcc about the fact that you are using math functions, because it is part of the basic standard library anyways.

That's just the way it is when working with different environments - sometimes you need to do things different from one system to another, because someone somewhere took some arbitrary decision to do things differently than some other system. It's not that one is definitely right and the other is wrong, just different.
