Re: LONG, LONG math - aka 64bit math....

yeah, for REALLY big numbers (like in some public key lengths)
even 2048 bits are not enough...
But you can always add 2048 bits at a time,
much as we humans add numbers by adding
them one digit at a time.
(Nearly) unlimited precision is easy.
I seem to recall that REXX does not have
a limitation on the size of numbers.
