* avutil/rational: Test av_rescale_rnd() with combinations of "special" valuesMichael Niedermayer2015-12-02
| | | | Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avutil/rational: use frexp rather than ad-hoc log to get floating point exponentGanesh Ajjanagadde2015-10-30
| | | | | | | | This simplifies and cleans up the code. Furthermore, it is much faster due to absence of the slow log computation. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* avutil: Add av_q2intfloat()Michael Niedermayer2015-05-26
| | | | | | | This function allows writing AVRationals as IEEE floats without the need of platform dependant float operations Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avutil/rational: Check that av_reduce() returns values within the requested maxMichael Niedermayer2014-12-29

* avutil/rational: avoid llrint() and rint()Michael Niedermayer2013-07-04
| | | | | | | | This should workaround issues with these functions on ia64 and sparc64 Fixes Ticket2713 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* av_d2q: Add a special case for |value| > MAX and |value| < 1/MAXMichael Niedermayer2013-05-31
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* av_d2q: Avoid llrint(), its not correctly implemented in old netbsdMichael Niedermayer2013-05-26
| | | | | | This should fix some fate failure Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* av_d2q: fix rounding for negative valuesMichael Niedermayer2013-05-25
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* av_d2q: Fix infinity checkMichael Niedermayer2013-05-25
| | | | | | | | The old check would fail on huge but not infinite values and the later code could then fail to handle them correctly in some cases. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
