Fixed build on Linux and macOS that was failing because of using std::to_chars and std::from_chars with floating-point values.

Browse source 
The old version of GCC and Clang support only integers to be passed to std::to_chars and std::from_chars. macOS older version of Clang doesn't support std::from_chars at all. So for Linux and macOS, it was replaced std::from_chars with strtod and temporarily was replace std::to_chars with snprintf.
