S. my current version of the test code is: ` [[assume(_view._Unchecked_end() - _view._Unchecked_begin() >= 1)]]; double val; constexpr auto options{fast_float::chars_format::general | fast_float::chars_format::no_infnan | fast_float::chars_format::disallow_leading_sign}; const auto res = fast_float::from_chars(_view._Unchecked_begin(),...

I added an improvement test with parser emulation. P. S. In real code of mathematical processing engine, my patches also give significant improvements (this is from MSVC, not tested on...
