Use "rint()" instead of rounding manually with "+ 0.5"

rint() is "round to nearest integer", and does a better job than +0.5
(followed by the implicit truncation inherent in integer casting).  We
already used 'rint()' for values that could be negative (where +0.5 is
actively wrong), let's just make it consistent.

Of course, as is usual for the messy C math functions, it depends on the
current rounding mode.  But the default round-to-nearest is what we want
and use, and the functions that explicitly always round to nearest
aren't standard enough to worry about.
