I compared the results with wolfram Alpha, and also with an open source arbitrary precision calculator, which matches Alpha results.
Decimal is *not* an arbitrary precision data type, so you can't expect exact results from it. You can set the precision to be very large, but it's still essentially a floating point type, and as such you can expect the last few digits to depend heavily on the details of the algorithm used. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
