StrToNum | number conversion library , for char and wchar_t strings

StrToNum is a C++ library. StrToNum has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A header-only library to convert char and wchar_t text strings to numbers. It is completely based on the Microsoft's std::from_chars implementation from the standard header. The one significant difference though is that the ability to work with wchar_t type was added, because the C++ standard doesn't provide this functionality at the moment. StrToNum features std::(w)string_view as an input, so you are no longer obliged to have only null-terminated strings, which is mandatory in all std::strto* functions family. StrToNum also recognizes 0x and 0X prefixes as hex strings, when iBase is 0 or 16, which std::from_chars doesn't. As a return type StrToNum uses either std::optional (by default) or a newish and very convenient std::expected (through /std:c++latest), which either holds converted number or a from_chars_result struct, in case of converting error. Both these types are very similar. To use the std::expected version put the #define STN_USE_EXPECTED line before #include "StrToNum.h". Basically StrToNum is a thin wrapper over the std::from_chars machinery, with the convenient interface and the ability to work with wchar_t strings. Non-allocating, non-throwing, locale-independent.
