[FFmpeg-devel] [PATCH 0/2] initial support for hypot

The hypot function is very useful since the naive sqrt(x*x + y*y) has overflow
and hence mathematical accuracy issues, see e.g
1/2 adds configure+libm support. The fallback is currently a naive one,
and may be improved in a separate patch.
2/2 gives a simple illustration in avutil/eval. It may be useful elsewhere as well.
Ganesh Ajjanagadde (2):
configure+libm.h: add hypot emulation
avutil/eval: change sqrt to hypot
configure | 2 ++
libavutil/eval.c | 2 +-
libavutil/libm.h | 8 ++++++++
