Alain,
The patch I just posted fixes the problem on my machine completely. The problem
with the previous version of the patch (other than the source mistake you found
;) )has something to do me coding in the 0.5 special constant. Replacing it
with a literal 0.5 constant works.
I also extended the definition of PI 3 places to avoid drift of the values when
it gets an input significantly greater or less than PI and -PI.
Let me know how it works for you.
Thanks.
Conn
