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.
