Dude, after forcing -std=c++20, the compiler still can't find a reference for std::ostream::operator<<(float)...

Do I have to link with some non-standard library? There doesn't seem to have any numbers.a included with gcc.

Weird, it should be standard C++20. Hope are you invoking gcc?

Edit: be sure to call g++, not gcc.

Oh, that's right, I was using gcc.
