Hmm. I'm not sure that it ever got documented properly. There may still be an open documentation issue somewhere. There's not really much wiggle-room for changing the implementation: the behaviour of the "g" formatting for Decimal objects is following the specification of "to-scientific-string" from the Decimal Arithmetic spec that the decimal module is based on: http://speleotrove.com/decimal/daconvs.html#reftostr One of the principles articulated there is that to-scientific-string should be faithful, so that conversion to string and back doesn't lose any information. That precludes chopping significant trailing zeros. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42429> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
