Bob, you're most welcome!

Here are the 16-digit constants for sine:

-8.86096047786772E-07
+1.34958277546461E-11
-9.73258222092326E-17


Regardless the exta digits, the maximum error should stay around 2E-10. Anyway, some rounding errors should be eliminated, so these should be worth trying.

Regards,

Gerson.

Edited to correct a mistake (2E-10, not 2E-9).
