@ldionne should we enabling floating point support by a CMake configuration option which is ON by default. The tables aren't small and it could add bloat for embedded devices.

Hmm, for now I'd make them available everywhere, and in the future, I'd add a knob if that is deemed useful. I believe that most embedded implementations will dead strip everything away if they don't use it anyways, so that might never be an issue.

Once this is shipped, we'll only be missing from_chars, right? We should be able to use https://github.com/fastfloat/fast_float to do that. We can ask if Daniel Lemire would relicense his code.

assuming long double is 64 bits is stupid.

Thanks also for fixing the return statement of testConversionSpan() in span.pass.cpp
