aba93f306f Additional compile time cleanup. When FASTFLOAT_ONLY_POSITIVE_C_NUMBER_WO_INF_NAN is enabled we assume that we are in parser code with external loop that checks bounds. 
Function cpp20_and_in_constexpr() now is really compile time evaluated. TODO fix warnings.

bc3f331938 # cleanup. 2025-03-06 23:02:50 +03:00
IRainman
9ebac23081 Added a config option FASTFLOAT_ONLY_POSITIVE_C_NUMBER_WO_INF_NAN for faster and more compact code parsing numbers with input support only positive C/C++ style numbers without nan or inf. That case is very useful in mathematical applications, game development, CSS parsing, embedded code, etc... 
Additional improve in constant initialization.

5167a5029d Change smallest_power_of_ten to -64 for floats. 
`18446744073709551615e-65` rounds to `0`, and it is the largest possible value with exponent `-65`. Therefore, we can assume the minimal exponent for which we don't round to zero actually is `-64`.

Fix warnings with -Wundef 
- FASTFLOAT_ALLOWS_LEADING_PLUS and FASTFLOAT_SKIP_WHITE_SPACE are not defined by default, and compiling with -Wundef is emitting warnigns like "FASTFLOAT_ALLOWS_LEADING_PLUS is not defined, evaluates to 0".
- Likewise for FASTFLOAT_VISUAL_STUDIO, change checks to use #ifdef for that like in other places.
- __cpp_lib_bit_cast and __cpp_lib_is_constant_evaluated are not defined pre-C++20, and are emitting a warning too.
