We need to make sure that the large table is included only once per project. I.e., if several compilation units include our header, we want the large table to appear only once in the final executable or library. That is why we use the strange template construction with an unused parameter.

Ok. I am satisfied that it does not obviously create bloating. |

I added
constexprto functions where the definitions need no or just minimal change.I added the
FASTFLOAT_CONSTEXPR14to for functions that need at least C++14 to be markedconstexpr.
