You almost never want to compare floating point values like that. See
e.g. compare_float() in dlls/ddraw/tests/ddraw7.c for a better (if
perhaps not quite perfect) way. E.g. for the FLT_MAX case this only
works because you happen to get an exact match. "1e-30" is a double
instead of a float. Of course this is probably copied from the
existing tests, so I suppose I can't complain too much.
