Software Bug: Shift, (a b/c) key sequence not working in CAS mode in HP Prime Virtual Calculator

HP Recommended
HP Prime Virtual Calculator
Microsoft Windows 7 (64-bit)

Shift + (a b/c) key combination does not work in CAS mode, i.e. one cannot input e.g. 36°40′20″. After Shift is clicked and (a b/c) key is clicked afterwards nothing happens. There are no errors and no crashes. This key combination appears to be ignored silently.

Environment:

OS: Windows 7 SP1 Home Premium 64bit

HP Prime Virtual Calculator: 64bit Build 2.1.14181 (2018 10 16)

 

Thanks in advance for your help.

Hi!, @User8034 :

You needed press ...

Write --> 2.4 and ENTER Key = 2.4

Now, press --> Shift and a b/c Keys = 2°24'00"

If convert newsly --> copy --> 2°24'00" and press ENTER key

Now press --> Shift and a b/c Keys = 2.4

See the use of Shift and a b/c in the User Guide from ... http://h10032.www1.hp.com/ctg/Manual/c05332710

Entry and edit keys - page15

Kind Regards !.
Have a nice day !.

@Maké Are you talking about the actual device (physical HP Prime) or its PC emulator software (aka HP Prime Virtual Calculator). Bug reported is only for the emulator. Pressing Shift key followed by (a b/c) key does not work.

Example: Entering 36°40′20″ is supposed to be 36, Shift, (a b/c), 40, Shift, (a b/c), 20 Shift, (a b/c). Currently, this is not possible to do at all with HP Prime emulator.

 

P.S. HP Prime PC emulator software download: ftp://ftp.hp.com/pub/calculators/Prime/

Hi!, @User8034 :

I have the Physical an Emulator calculator in the ultimate version.

You needed entering for --> 36°40′20″ --> 36, Shift, (a b/c), 40, Shift, (a b/c), 20 Shift, (a b/c) and ENTER key.

Then press Shift and a b/c keys and obtein ... 36.6722222222 and if press a b/c obtein --> 6601/80

Click the CAS key to enter CAS mode first, and then you'll notice that Shift, (a b/c) key sequence no longer responds.

But why is it not supposed to in CAS mode? What's the problem?

P.S. I'll update the title and report details to denote clearly that this is in CAS mode.

Check, this file ... http://www.hpcc.org/calculators/hpprime/HP_Prime_User_Guide_EN.pdf

See, in pages 26/27 and you see what is not in CAS (Computer Algebra System).

[Shift] [a b/c] only inserts the degree/minutes/seconds symbols, and converts between decimal and sexagesimal notation, in Home view, not in CAS view.  This is true of both the emulator and the hardware calculator (all firmware versions).  This fact can be (barely) seen in that key's Help screen: press Help, Keys, [Shift], [a b/c] and notice that it says "in the Home view" buried in the text.  So the bad news is that it doesn't work in CAS (not due to a bug, but by design) and never will.  The good news is: it DOES work in Home, which is where floating-point approximate calculations are intended to be performed... such as calculating with angle measurements.

@Joe, In Chapter 23 (Functions and commands) section on [Shift] [a b/c] reads:

I understand this as it should work in both. Have you tried this on a physical HP Prime?
