I have an alternative implementation of the gamma function you might like, 2 + 3 - you get 8.8818e-16 also, 1 enter 1e-13 + 1 - to get 9.9920e-14 both of these are really annoying. here are some things that increasingly bug me (and you).
i did the same in my implementation of scicalc but more and more recently i am going away from binary back to bcd. i can well understand your use of ieee754 not least from a performance point of view. firstly, your wrestle with bcd vs binary is something ive been struggling with for some time. I have a few ideas that might help it to become even better. i like the palm version, it works well, although the beep is a bit loud. Message #3 Posted by hugh steers on, 6:39 p.m., Good job! I really hope that the OpenRPN people sees this! This would be great on a small Embedded Linux device. In response to message #1 by Thomas Okken Message #2 Posted by Erik Ehrling (Sweden) on, 2:32 p.m., And best of all, it's freely redistributable and requires no ROM image.

Meanwhile, what you do get with Free42 is: speed (no Saturn emulation layer slowing things down I rewrote the entire HP-42S in C) and PalmOS, Linux, and Windows support. All these things are planned for the next release, probably 1st quarter 2005. It's not as pretty as Emu42 yet, and there's no printer emulation yet, nor is there a facility for importing/exporting programs (RAW or otherwise). I just finished version 1.0 of Free42, a new HP-42S emulator. Message #1 Posted by Thomas Okken on, 1:35 p.m. RP: Swaps between rectangular and polar modesĬonstant Libray implemented through a programmable menu.Free42 version 1.0 released The Museum of HP Calculators The program adds the following functions:ĬONJ: Computes the conjugate of a complex number So far, the purpose of this function is toĬreate a CUSTOM menu with some commons complex funcions. If no new X-register is introduced with the keyboard, the current value in X-registerĪs it has already assigned a unit, it can be converted to a new unit just pressing the Select the unit applicable for the X-register and afterwards select the conversion unit.

The summary of the functions are (the details of input/output of each function is embedded in the source code): The main idea of this collection is to make use of the CUSTOM menu as much as possible in the same way that it can be done in HP48G.

Notice that the code uses functionalities available in Free42 v2.5.24. These functions are an exercise to explore the capabilities of Free42. I have published in Gitlab a collection of functions organised by topics in:
