Ganesh Ajjanagadde	20a30077c3	avutil/mathematics: correct documentation for av_gcd av_gcd is now always defined regardless of input. This documents this change in the "documented API". Two benefits (closely related): 1. The function is robust, and there is no need to worry about INT64_MIN, etc. 2. Clients of av_gcd, like av_reduce, can now be made fully correct. Currently, av_reduce can trigger undefined behavior if e.g num is INT64_MIN due to integer overflow in the FFABS. Furthermore, this undefined behavior is completely undocumented, and could be a fuzzer's paradise. The FFABS was needed in the past as av_gcd was undefined for negative inputs. In order to make av_reduce robust, it is essential to guarantee that av_gcd works for all int64_t.

Ronald S. Bultje	a1245d5ca1	mathematics: Don't use division by zero in NAN/INFINITY macros Some compilers, MSVC among them, don't recognize the divisions by zero as meaning infinity/nan. These macros should, according to the standard, expand to constant expressions, but this shouldn't matter for our usage. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Carl Eugen Hoyos	15bde06084	Revert "mathematics.h: remove a couple of math defines" This reverts commit `a2b186a188`. The defines were present for several years, removing them without a version bump may break API. (Fixes MPlayer compilation.)	13 years ago
Janne Grunau	a2b186a188	mathematics.h: remove a couple of math defines While these defines are not defined by the C standard they are standardized as X/Open System Interfaces Extension. We use the appropiate _XOPEN_SOURCE define to make them available. They seem to be available on all FATE configs since the constants are used in files where mathematics.h is not included.	13 years ago
