The effect of that would seem to be that no program can safely use <br>
floating-point expressions in constant expressions at all, in case the <br>
implementation chooses to evaluate with less range or precision and so <br>
give them undefined behavior.<br>
<br>
I think we need a demons or ghosts paper to replace this "shall be" (in <br>
6.6.1) by "is" (or some similar change), since if there is UB here, there <br>
should not be; the implementation should not be permitted to use less <br>
range or precision in the translation environment.<br>
