+ | I've been developing the 4-banger I uploaded recently and am approaching a worthwhile scientific calculator. Walter Bonin and I have been working on the keyboard layout and function set and I've been doing the implementation. | ||

+ | |||

+ | The calculator is based loosely on the HP-34c with some of the more modern functions added; it also has complex operations like the 32/35 series but over a much wider range of functinos. Additionall, the device supports superset of the HP-16c integer mode functionality. It is programmable with 500 steps of program memory (every instruction taking but a single step) and 100 storage registers. | ||

+ | |||

+ | Registers and the stack are 16 digits decimal arithmetic. | ||

+ | Internal operations are performed in 39 digit decimal arithmetic with an extended exponent range. | ||

+ | Statistical accumulations are done in 34 digits decimal arithmetic which should avoid rounding and cancellation problems. | ||

+ | |||

+ | Some special functions are log gamma, beta, zeta and Labert's W -- the latter real mode only at present but the former are defined over the complex plane. | ||

+ | |||
