The issue is that the implementation of round includes multiplying the
number by 10**ndigits, thus unnecessarily losing some precision for
large numbers within the IEEE754 double limits. This means that even
smaller numbers can produce these results for higher ndigit values, eg.

>>> round(56294995342131.5, 3) #one less digit
56294995342131.508

In the submitted patch I used modf to split the number and keep the
integral intact.
