I don't very much like that code -
Me neither, just wanted to address the issue.
but OTOH I'm thinking to use double precision to compute the table this time around, so whatever imprecision there is should be minimal :)
Also, instead of accumulating the phase you should calculate it for every point:
#ifndef M_PI #define M_PI 3.14159265358979323846264338327950288 #endif
...
for (int i = 0; i < COSTABSIZE + 1; i++) fp[i] = cos(2.0 * M_PI * i / (double)COSTABSIZE);
This should ensure that the table is symmetric, unless the underlying cos() function is broken :)

Sounds good to me!
Just to be sure, you will also try to make the new table symmetric, right? See https://urldefense.com/v3/__https://github.com/pure-data/pure-data/pull/106/... .
