You could use unsigned ints, whose arithmetic wraps, to deal with the overflow.

I'd still be curious about any theories of storage.

[charcircuit]

Javacript doesn't have an unsigned int datatype. The numbers in the article were doubles.

you cant swap doubles like that though... b/c if any of them is a NaN or an infinity, it breaks down.

It works for integers (and pointers)

[charcircuit]

It also breaks due to rounding even if you don't have NaN or Inf.
