[Per W. <pw...@ia...>]

And that is why I observed that limes 1/x reaches different values when x
reaches zero from positive and negative side, i.e. we either have to
conclude that +infinity is identical to -infinity, or we have to think of
1/0 as just "undefined". In short, thinking of 1/0 as infinity is a
simplification of the problem - my original point.

When talking about division by zero in software-development terms, the
IEEE 754 floating point standard defines:
+n/0 -> +infinity
-n/0 -> -infinity
0/0 -> not a number (NaN)
