You have to remember what -inf and 0.0 actually mean: respectively
"a negative number too small to represent" and "a positive number too
close to zero to represent."  And indeed, if you take the log of a number
too close to zero to represent, such as 1/(10^10^10) you will indeed
get a number too small to represent.

9/0 is indeed inf, though 9%0 ought to be an error (in Q it's inf).
