Well, all HP calculators with 12-digit BCD arithmetics I know of use 15 digits internally, just as the 10-digit devices use 13. So I think it's safe to assume that the Prime doesn't behave differently here. ;-)

As explained here the HP 48 math library (Saturn assembler) has been rewritten In C to be used in the new HP calculators starting with the HP 20b/30b. This explains why the results of the HP Prime in Home mode are the same as the HP 48.
