Re: Are these bugs fixed in Mathematica 8 ?


On my copy of Mathematica 8, I get the right answer:

In[1]:= 10^80000<Exp[1.5*^-323228465]
During evaluation of In[1]:= General::unfl: Underflow occurred in computation. >>
Out[1]= False

In[2]:= $Version
Out[2]= 8.0 for Mac OS X x86 (64-bit) (November 6, 2010)
