    Question What was the library for math.h functions?

    I tried "-lmath" but that didn't work out, tried looking for it via google but who'd of thought that even the official docs don't even mention it let alone every other link I tried be it a guide or something else

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    From man 3 pow (Just one of the functions available from the math library):
    POW(3) Linux Programmer's Manual POW(3)

    NAME
    pow, powf, powl - power functions

    SYNOPSIS
    #include <math.h>

    double pow(double x, double y);
    float powf(float x, float y);
    long double powl(long double x, long double y);

    Link with -lm.
    ...
    The man system is the programmers friend! ;^)
