Yep.  There&#39;s not much consistency in inf/nan handling across 
platforms,<br>
though the situation is slowly getting better.  math.pow makes an effort<br>
to handle these special cases correctly (for some value of correctly), and<br>
it would probably make some sense to have the builtin pow behave the same<br>
way.<br>
<br>
Would you be interested in contributing a fix?<br>
