Gennaro Prota	a841869405	Remove a use of std::strcpy() to avoid a C4996 warning from MSVC	2025-10-24 11:00:21 +02:00
Alexander Grund	3613e9578d	Fix standalone build with Clang The config.hpp uses `BOOST_LIBSTDCXX_VERSION` which isn't defined in standalone mode so `BOOST_STATIC_STRING_NO_CXX17_HDR_STRING_VIEW` will be defined. This then causes build failures for code expecting the availability of string_view.	2025-10-24 10:11:37 +02:00

Gennaro Prota	815678e1e7	CI: Test C++26/2c again	2025-10-23 16:49:48 +02:00
Gennaro Prota	2cc22bf5a8	Align to_static_[w]string() with C++26 std::to_[w]string() C++26 specifies that std::to_string() and std::to_wstring() format floating point values as if using std::format(). This commit updates the internal conversion helpers to match that behavior, using std::format_to_n() for efficient, allocation-free formatting directly into the static_string/static_wstring buffer. Fallbacks using snprintf()/swprintf() remain active for pre-C++26 builds. This ensures consistent formatting across standard and Boost APIs.	2025-10-23 16:49:48 +02:00
Gennaro Prota	d6f976a7df	Fix the sizes of the strings returned by to_static_string() and to_static_wstring() for floating point values	2025-10-23 16:49:48 +02:00

Gennaro Prota	9c5d69475d	Implement the arithmetic conversions in terms of resize_and_overwrite() Reason: Performing the conversions without accessing private members, providing a model for users to implement their own with comparable efficiency.	2025-10-09 17:45:16 +02:00
Gennaro Prota	300781d954	Add a resize_and_overwrite() member Reason: This is in preparation of the next commit. See its commit message.	2025-10-09 17:45:16 +02:00
Gennaro Prota	cd1a1a41c3	Don't use an additional buffer in the arithmetic conversions In the case of the floating point conversions, this effectively avoids a copy of the buffer contents. In the case of the integer conversions, it doesn't eliminate the copy, but still removes the extra buffer. This fixes issue #65.	2025-10-09 17:45:16 +02:00
