std::cerr can't print float variable

Hello, world!

This is my first post on this site so don't blame me in anything.

I am writing a program that is supposed to operate with matrices and to use OpenGL framework for drawing them. Honestly, it's just for practice. Anyway, I tried to compile it and, of course, it didn't run well. Inserting as many logging as I could, I found out that my std::cerr can't print float value. I really got no idea how that may stop working. I have made some deep researches on my little code like changing variables to their values, coding external programs using same functions and so on; and found even more unbelievable thing that there's no reason for this. ABSOLUTELY. Perhaps, since robots can't harm human being, they troll it evilly. Thank you, Azimov.
