In normal arithmetic, yes, sgn(0) is 0, but here we are in floating point arithmetics where sgn(0) is 1, see: https://en.wikipedia.org/wiki/Floating-point_arithmetic#Signed_zero
But FFSIGN(0) results as -1, which is never correct. -Ulf _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
