Not my merit, it is based on Ken Emery's routine published in MCODE for Beginners.

Hello Angel,
I looked that routine up, it performs the exact same steps as the PPC ROM routine, but coded in MCODE. It does not use extended precision (to my untrained eye, I don't speak MCODE), so I wonder how it got the right results? Or maybe you 'tweaked' it?

You're correct, I use a 13-digit division routine in QREM, which seems to make the difference.

Cheers,
