This is obviously wrong, 12 decimal places are using 12*4=48 bits.

User numeric results have 12 digits, whereas internal calculations are done on 15 digits, for all Saturn-based machines, whatever RPL, RPN, Algebraic or BASIC. And whatever based on System RPL or pure assembly language firmware. The math core is basically unchanged since the HP-71B.
