Yes, for floating-point numbers. This is due to inherent imprecision
in how floats are represented in hardware. If you can live with being
a touch off that many decimal places out, you can just clean up upon
printing with something like:
>>>print "%0.1f" % (a)
1.1
for your value of a above. If you don't want to deal with this cruft,
you may want to give the Decimal class a gander:
>>>from Decimal import *
>>>setcontext(ExtendedContext)
>>>a = Decimal('1.1')
>>>a
'Decimal("1.1")'
>>> print a
1.1
