wow- I never would have expected that... It seems that anyone who has a computer program dividing by zero would want an exception raised or at least have an NaN generated. Generating "0" makes no sense- In my scenario, for instance, the function limit was towards 1, so generating a zero is mathematically seemingly completely nonsensical.... Thanks for straightening me out, kens :-)

In floating point arithmetic 0.0 isn't zero: it represent a range of numbers around zero, so it makes a little sense for 0/0.0 to return 0.0. I still think that raising an exception would be preferable.

To be pedantic, it doesn't make any sense to return 0.0, but it does make some sense to return 0. I'm sure that's what you meant though.

It's 0.0/0.0 that gets my head spinning. If only 'Whatever' were a valid number.

Well, it depends.

  lim{x -> 0}(x/x) = 1
  lim{x -> 0}(x/0) = NaN
  lim{x -> 0}(0/x) = 0
