if with "hardcoded" you mean a string constant, then the answer is no. "s" is a pointer to any c string, the const part only means that gensym() promises not to modify the string. google "const correctness".
Can this convert floats to symbols?
use a char array together with snprintf, e.g.:
char buf[100]; snprintf("foo-%f", sizeof(buf), someFloatValue); // NOTE: you should check the return value, if you want to be safe, see https://linux.die.net/man/3/snprintf gensym(buf);

I have read it. I understood that the "const" part of "const char *s) means it can only take an actual hardcoded string. Can this convert floats to symbols?
