Close, but not quite: the inverse of zero is zero.

Uh, what? I thought that the point of an inverse is that multiplication gives 1 -- that's certainly what I read at http://en.wikipedia.org/wiki/Modular_multiplicative_inverse

Wouldn't the modulo inverse of 0 be a NaN just like the result of 1/0?

I believe this to be more relevant: http://planetmath.org/encyclopedia/AdditiveInverseOfTheZeroInARing.html
