    For floating points, trapping is a different, more complicated
    story.  If is_iecxxx is true, then division by zero would not trap
    (infinity).  If is_iecxxx is false, we don't know (VAX may trap for
    0/0 -- I have to check).  For most cases (i.e. IEE-754), trapping
    for floating points have to do with whether there is a support for
    signaling NaN.
