* gaol/gaol_interval.h: corrected bug in is_symmetric()
2009-05-07 Frederic Goualard <[email protected]>

interval is considered as not symmetric.
2009-03-06 Frederic Goualard <[email protected]>
* gaol/gaol_parser.cpp: creating an interval from "inf" or "-inf" leads to [dmax, +inf] or
[-inf, -dmax] instead of <inf, inf> and <-inf, -inf>
2009-03-03 Frederic Goualard <[email protected]>

if the interval is composed of three floats a<c<b and c is closer to
a than b, then rounding upward would return b instead of c.
* gaol/sysdeps/gaol_interval_ix86_cpp.h (midpoint): corrected a bug in midpoint():
if the interval is composed of three floats a<c<b and c is closer to
a than b, then rounding upward would return b instead of c.
