Re: C47: Root calculation methods

Two things:
  • to get a result for 1. you need to enable complex results by setting the flag CPXRES
  • the difference between the cube root and the power to 1/3 is not new nor specific to the C47, see for example this discussion on the hpmuseum

Re: How to make the APPEND symbol on DM42

All the differences you’ve mentioned are not specific to the DM42 , they are differences between the HP-41C and the HP-42S. ARCL X vs ARCL ST X * They seem the same. And similar key presses to get this on 42. Are they the same? Yes they are the same. * If they are the same, is there a way to get ARC...

Re: WP43 Bug Reports and Maintenance

That bug will take some nights probably to find out so don't hold your breath. No need to wait several nights, I've found a way to easily reproduce this issue: go to CLK menu press TIME press 1 - press Up SETTIM Now you can see that the time is frozen to the previous value, it doesn't update to the...

Today, for example, I did not see it on first ON after using it last night. Today it updated to the correct date/time almost immediately, <<1s.
At what time did you turned it off last night and when did you turned it on today?

Re: C47 tagged angles

A few questions on tagged angles. These are with respect to keystroke programming. I think there are only three possible tags, but please let me know if there are more. The three I know are degrees, radians, and multiple of π radians. There are two others: grad and dms. 1. Is there a way to remove ...

Re: My Two Wishes Swiss Micros - Everyone reply with yours?

You suggest to fill another pocket with a bigger pocket calculator - I doubt that will ever happen. Look: a major fraction of the above carry their smartphones like pendants since they prefer to look lean, not blown up by big filled pockets. So there may be a market for pendant calculators :mrgreen...

Re: WP43: STATUS Indication (Poll)

To add some context there was a rule defined long time ago by the WP43 team stating that flags which have their status already visible in the status bar should not be indicated in the STATUS display as this would be redundant. This is why in the latest implementation neither B/OVERFL, C/CARRY, I/CPX...

Re: testPgms.bin

On the C47 windows emulator all is OK. The programs from testPgms.bin are properly listed under "PROGS" but nothing appears on the DM42/C47 real calculator. I confirm this is a bug in the latest versions of the C47 firmware for the DM42. However there is a simple workaround: if you press ...
