I think it's:
if (f > 0)
return floor(f + 0.5)
else
return ceil(f - 0.5)
Otherwise -1.5 doesn't work like round() does. Glad we have a test to
verify this :-)

In the FreeBSD manual pages ceil() and floor() are mentioned to be
according to C90 and C99, while round() and trunc() are only in C99.
How about strtod(), it's only in C99 as well.
