On: What's the difference between 0/0 and 1/0?

Well, in javascript 0/0 == NaN while 1/0 == Infinity.

An interesting thing is they have the value -0 so you can set a=-0 and 1/a returns -Infinity.

This is not only javascripts behavior, it is the IEEE standard for floating-point arithmetic which most modern hardware and software strictly adheres to.

Except that is defined, standard IEEE 754 behavior and is true on nearly all programming languages.
