Someone pointed out that this isn't correct, and then deleted their comment. (?)

I now think the behiviour I ascribed to print, is actually what repr does. I'm not sure about print, but I guess it is just rounding to a certain number of places.

    >>> from decimal import Decimal

    >>> Decimal(0.1+0.2)
    Decimal('0.3000000000000000444089209850062616169452667236328125')

    >>> Decimal(0.3)
    Decimal('0.299999999999999988897769753748434595763683319091796875')

    >>> Decimal(0.300000000000000000000000000001)
    Decimal('0.299999999999999988897769753748434595763683319091796875')

    >>> print 0.300000000000000000000000000001
    0.3

    >>> repr(0.300000000000000000000000000001)
    '0.3'

    >>> D(0.30000000000000004)
    Decimal('0.3000000000000000444089209850062616169452667236328125')

    >>> repr(0.299999999999999988897769753748434595763683319091796875)
    '0.3'

    >>> repr(0.30000000000000004)
    '0.30000000000000004'

    >>> print 0.30000000000000004
    0.3
