139 2019-01-01 13:09:52 dmarschall /trunk/ Bugfix: Function c2d() now behaves like in Filter Factory. Implementation changed from atan2(-y,-x) to atan2(y,x).  
135 2018-12-31 04:05:40 dmarschall /trunk/ Trig tabs are now calculated during Filter startup rather than during compile time.
Reasons:
1) It is more safe in regards to multi platform build (if the gentab.c generation was forgotten), since TRIGAMP is defined differently between Windows and Mac, and therefore, costab[] and tantab[] would be wrong.
2) The usage (table with double values instead of value_type value amplified with TRIGAMP) is more universal. For example, with this new table, the functions r2x() and r2y() can now be calculated faster.
