I found this paper:

http://http.download.nvidia.com/developer/Papers/2005/FP_Specials/FP_Specials.pdf

That seems to suggest 0 * +Inf = NaN.

But, it also mentions that this applies to hardware/implementation that
supports floating point operations and floating point special numbers like Inf
and NaN. I'm not sure, but maybe in the old d3d8 days there was no floating
point and thus no NaNs or Infs, so, basically, divide by zero was clamped to
max value like "1.0" or something like that?
