Hi, the following program prints "1e-01". Furthermore, it prints "Error: 132" if I change `size` to 20. It prints the expected "0.1" if I change the two using declarations to use the standard facilities. Tested against the master branch, with MSVC 2022. Is this a bug in CharConv? #include "boost/charconv.hpp" #include <charconv> #include <iostream> int main() { // using std::to_chars; // using std::chars_format::general; using boost::charconv::to_chars; using boost::charconv::chars_format::general; int const size = 100; char buffer[ size ]; auto const r = to_chars( buffer, buffer + size, 0.1, general ); if ( r.ec != std::errc() ) { std::cerr << "Error: " << static_cast< int >( r.ec ) << std::endl; return 1; } *r.ptr = '\0'; std::cout << buffer << std::endl; } -- Gennaro Prota <https://prota.dev>
