Why should 1/0 be +Infinity? Think of 1/x at the limit as x->0 from the left and from the right

- chinpokomon 13y agoI still think the 1/0 problem can be solved if we step outside Euclidian geometry. It is undefined for the very reason you give. The Numberphile YouTube channel has an excellent video [1] discussing why x/0 is undefined and worth watching.

- mbq 13y agoWith IEEE floats, 0 has a sign which can be used to denote the direction of the limit; if you try 1/(-0) in any program or language with sane numerics (i.e. not Excel or other dumb calculator emulators), it should give you -Infinity.
