[issue13838] In str.format {0:#.5g} for decimal.Decimal doesn't print trailing zeros
Mark Dickinson dicki...@gmail.com added the comment:
IMO, the behaviour is fine; it's the docs that are unclear. The rules for
Decimal are different mainly because trailing zeros have meaning for the
Decimal type. (Decimal('1.250') and Decimal('1.25') are two distinct Decimal
objects, unlike float('1.250') and float('1.25').)
See also issue #7094.

[issue13838] In str.format {0:#.5g} for decimal.Decimal doesn't print trailing zeros
Mark Dickinson dicki...@gmail.com added the comment: Ah no, I take it back. I think (2) is fine---this is the usual preservation of trailing zeros where possible. (1) needs to be fixed (and issue #7094 was left open waiting for this fix). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13838 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13838] In str.format {0:#.5g} for decimal.Decimal doesn't print trailing zeros
New submission from py.user port...@yandex.ru:
http://docs.python.org/py3k/library/string.html#format-specification-mini-language
The '#' option:
For floats, complex and Decimal the alternate form causes the result of the
conversion to always contain a decimal-point character, even if no digits
follow it. Normally, a decimal-point character appears in the result of these
conversions only if a digit follows it. In addition, for 'g' and 'G'
conversions, trailing zeros are not removed from the result.
1)
import decimal
'{0:#.5g}'.format(1.5)
'1.5000'
'{0:.5f}'.format(decimal.Decimal(1.5))
'1.5'
'{0:.5g}'.format(decimal.Decimal(1.5))
'1.5'
'{0:#.5g}'.format(decimal.Decimal(1.5))
'1.5'
no zeros with #
2)
import decimal
'{0:#.5g}'.format(decimal.Decimal('1.5000'))
'1.5000'
'{0:.5g}'.format(decimal.Decimal('1.5000'))
'1.5000'
zeros without #
