HP50G on Emu48 : ->Tag for negative numbers - Gil - 11-17-2019 11:28 PM

I don't have a HP50G calculator, so that I use the great Emu48 application.

Question :
Is it normal that, with the HP50G on EMU48, the ->TAG command adds parentheses to the negative numbers (it does not add these parentheses on HP48-calculator or on HP48-Emu48)?

For instance :
-5 "AB" ->TAG returns
AB Sad

-5)
(but it returns the clearer
expression AB: -5 on HP48).

Regards,
Gil

Yes, it's the same on the real HP 50g. (Not that surprising, since Emu48 emulates the Saturn CPU running the same code as the real HP 50g. In fact, the real HP 50g also emulates the Saturn CPU.)

Not on mine

Not on mine

It does with the latest 2.15 firmware. What version is your HP 50g running? Maybe it depends on flag settings?

2.15

I suppose it is a matter of flags.
Mine are attached

The extraneous parentheses disappear when flag -79 is turned off (Textbook display mode).

Nice find

Just to clarify that Textbook mode is actually the opposite of flag -79. If you want to lose Textbook mode and the extraneous parentheses, you have to _set_ flag -79.

As always, HP was "right".
Thanks for your finding.

Strange enough, 48gx with Metakernel 2.30 does not show the extraneous parentheses, regardless textbook mode is engaged or not
