Mauricio de Alencar added the comment: According to the docs (http://docs.python.org/3/library/decimal.html):
"The decimal module incorporates a notion of significant places so that 1.30 + 1.20 is 2.50. The trailing zero is kept to indicate significance. This is the customary presentation for monetary applications. For multiplication, the “schoolbook” approach uses all the figures in the multiplicands. For instance, 1.3 * 1.2 gives 1.56 while 1.30 * 1.20 gives 1.5600." Therefore, if I request 2 digits of precision, I expect 2 digits in the output. In addition, the docs assert that "Decimal numbers can be represented exactly", which leaves me lost about you argument on whether some number is *exactly representable* or not. ---------- resolution: invalid -> status: pending -> open _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20502> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
