Package: manpages-dev Version: 4.16-2 Severity: normal Hello Tobias,
man modf says: Feature Test Macro Requirements for glibc (see feature_test_macros(7)): modf(), modfl(): _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L || /* Since glibc 2.19: */ _DEFAULT_SOURCE || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE However as I understand, it should be modff(), modfl(): instead. (modf is c89, but not modff) Cheers, -- Bill. <ballo...@debian.org> Imagine a large red swirl here.
