[Jprogramming] Largest Integer

[Roger Hui]

The values depend on whether you are running a
32 bit version of J or a 64 bit version of J.
The largest integer in the 32 bit version of J
would be the same whether you are running on
a 32 bit or a 64 bit machine.

3!:n gives you information about the sizes of
integers and floating point numbers.
