ndigits higher than 14 can result in values that are slightly too
large due to floating point limitations.  Converting to rational
for the calculation and then back to float fixes these issues.

The previous implementation could result in a returned
float that is 1/(10**ndigits) too low.  First try adding
one before dividing, and if that results in a value that is
greater than the initial number, then try the original
calculation.

Spec added for ciel, but the issue doesn't appear to affect
ciel, at least not for the same number.  If the issue does
effect ciel, a similar fix could probably work for it.

Previously, the result was incorrect:

4.remainder(-Float::INFINITY)
Before: => NaN
After: => 4

4.2.remainder(-Float::INFINITY)
Before: => NaN
After: => 4.2
