Is options.hpp missing <float.h>?

[Zachary1575]

When I build, I get the error of:

This is resolved by adding #include <float.h> to options.hpp.

...
#include <vector>
#include <string>

#include <float.h>

#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
...

Just wanted to confirm my build is not just incomplete or occurring through a misconfiguration. Note: I am working on MacOS Apple Silicon.
