[Jprogramming] Special code semantics

[Ben Gorte]

Hi J,

After

z =: 281474976711954

compare

<.z%32
8796093022249
and

z <.@:% 32

8796093022248

The second is "more correct", because:
   17j3 ": z%32

8796093022248.562


Unfortunately I had been using the first (and odd or even mattered a lot).
Is it a bug in J, or is it something I should have been aware of?

Greetings,
Ben
