As do I. I'd also point out that the ONLY requirement for long double according to the standard is that it has at least the same precision as double. Therefore, any implementation of these functions that is no worse that the double version is compliant. Once we have something meeting a minimum standard, then I'm very happy to see it improved, but having C99 functions missing now is just embarrassing while we're working on adding C11 features. David P.S. Someone said earlier that our clang still lacks some C99 features. Please point me at the relevant clang PRs and I'll be happy to work on them. There are quite a few open issues for C11 support, but C99 is, as far as I know, done.Received on Fri Jul 13 2012 - 10:55:04 UTC
