REXX uses decimal bignums, although I don't have a high-performance math library (for sin) that uses anything more than IEEE double precision. If I coded my own sin algorithm in REXX, I could go to whatever precision memory (and patience) would allow. Chris Angelico -- http://mail.python.org/mailman/listinfo/python-list
