Interesting.

zsh: number truncated after 18 digits: 9223372036854775809/-1
922337203685477580

No FPE in either case.

I'm having a hard time testing this because I can't get a mathematically
induced FPE, but recall that (quoting the doc):

   * The return status from function traps is special, whereas a return
     from a list trap causes the surrounding context to return with the
     given status.

So if you use

    trap 'return 1' FPE

you might avoid the infinite retry of the operation that Mikael reported.
