union ieee854_long_double
.
Gnulib module: ieee754-h
Portability problems fixed by Gnulib:
- This header file is missing on all non-glibc platforms:
glibc/sparc64 in 32-bit mode, macOS 14, FreeBSD 14.0, NetBSD 10.0, OpenBSD 7.5, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 11.4, Cygwin, mingw, MSVC 14, Android 9.0.
Portability problems not fixed by Gnulib:
- The substitute for this header file has not been tested for
long
double
and does not work on some platforms.
- The substitute for this header file returns nonsense on (now-quite-rare)
platforms that do not use IEEE floating point, such as Linux/m68k.
