# Why is 10/0 infinity in javascript?

Division by 0 is undefinable, so it should not be infinity. Or am I wrong?

See it as a limit, not as number. 1/0.1 = 10 1/0.01 = 100 1/0.001 = 1000 1/0.000..01 = extremely big And since a computer cannot represent ifinitely many digits 0.000...01 is basically zero and similar the extremley big number is "infinity"

Vicious in language. The proper term for x/0 if x not equals 0 is undefined. 0/0 is indeterminate. undefined not equals indeterminate. People just user infinity term in this case wrong in literature over and over. That is the reason. The proper way to avoid this is throw a error. Can be just a design call ? it can but just makes confusion.

Matthias i suppose we can do this with negative numbers too and name what we call "negative infinity".
