My hypothesis was that this "bug" was caused by a limtation of the FPU to handle values greater than 14 digits. My tests (and I've done a number of them since my last post) seem to confirm this hypothesis. Therefore, my conclusion must be that this is a problem with the capacity of a double precision floating point number.

Hi George,

I know that a full year has passed since you wrote this all and challenged Fabio to give PROOF. Fabio has indeed reacted and did his upper best to give proof. I'm wondering, why didn't you react to his proof? Or did you?
