I spotted it while rewriting a program 'FXND' (meant to duplicate the oldRPL command of the same name) to take advantage of the new commands. Here's the code for it:

<< STKPUSH DUP TYPE -> t << CASE t 10 == THEN 1 END t 56 == THEN IF OBJ-> NIP { / } 1 GET SAME NOT THEN STKPOP 1 END END 24 DOERR END >> >>

If I do:

0.6 ->Q FXND IDIV2

I get:

00000000

3

This does not occur when I do:

'3/5' FXND IDIV2

So the problem must lie in ->Q somehow. But that may only be a symptom, because numbers consisting of multiple 0's probably shouldn't exist in the first place?

I found it myself 2 days ago and fixed it, it was a denormalized zero that confused the text conversion.
Will come out in the next release.
