- [Commit-gnuradio] [gnuradio] 01/13: Corrected the fast_atan2f function. Recalculated the table and corrected some errors in the code. Error before correction: <0.111 degrees. Error after correction: <8.20E-5 degrees Some QA tests failed after correcting fast_atan2f function. The tests were also fixed., (continued)

- [Commit-gnuradio] [gnuradio] 04/13: Checking for NaN takes too much time. With some incompatibility to cmath atan2 for some NaN/Inf combinations the performance is better now. This change should not have any impact in SDR related things. It is only for checking NaN/Inf values., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 13/13: logger: fixed a problem with the Python loggers not respecting the log_file and debug_file settings in the logger preferences file., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 07/13: runtime: math: reset a QA test for the fast_atan2f for mixed nan/inf input., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 06/13: runtime: math: in fast_atan2f, moved nested if that checks for divide by zero out into its own check., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 08/13: qtgui: compare current time domain x-axis unit with new unit to ensure time scale update., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 03/13: cleaned the code, git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 11/13: filter: fixed default filter for rational_resampler., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 12/13: filter: adds documentation to using the rational resamplers., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 09/13: digital: fixes issues with the constellation soft decoder, specifically how the decisions are calculated in the C++ code and some issues with the QAM16 constellation in particular., git, 2014/12/04
- [Commit-gnuradio] [gnuradio] 10/13: digtial: adding example to explore the constellation decoder and soft decoder for different constellations.,
