That means: - float and long double versions of math functions - complex number support - type generic math - hopefully fewer bugs :-) Code is based mostly on freebsd, and in some cases on openbsd, both of which originally derive from fdlibm (Sun). The code has been cleaned up quite a bit and reorganized to eliminate the confusing and often arbitrary k_/s_/e_/etc. filename system and instead focus on what public interface or internal __-prefixed function the translation unit is implementing. At this point arch-specific assembly is minimal, even moreso than previously in musl. Now that the code is in-place and working, we can begin to optimize it again, and be more careful not to introduce incorrect optimized versions. This brings us to the point of supporting almost every interface in C99 and POSIX base. The few remaining ones will be addressed soon. If no bugs are found in early testing of the new math library integration, I'll plan to release 0.8.7 sometime soon, hopefully within the next week, and aim to have the finishing touches to get us to 0.9-series completed within around a month. Rich
