Solved!

Converting from Degrees <> Radians on HP-Prime

HP Recommended
HP Prime

Looks like I'm not the first to ask this question:

I spotted the article:  

http://h30434.www3.hp.com/t5/Calculators/hp-prime-deg-to-rad-rad-to-deg/m-p/3315481#M4826

 

Problem is,  the CONVERT()  doesn't seem to work when you are in RPN mode.    If I switch to textbook mode it works,  if I try in RPN,  I get a syntax error.   I suspect other catalog entries do not work  in RPN mode but haven't tested.

 

I was pretty surprised to find that the HP-Prime doesn't have a key/menu selection to convert from degrees to radians and visa versa.

Hi!, @garbel:

 

1) Configure your HP PRIME, for use with RPN.

 

This example, is for converting minutes, to hours ...

2: 1_h

1: 30_min +

 

You obtein ... 

1: 1.5_h

Kind Regards !.
Have a nice day !.

Hi!, @garbel:

 

The example, is extracted, from ... http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv021.cgi?read=251800

 

In RPN, you can use CONVERT.

 

1: 10_deg

15_rad

 

Type CONVERT or convert and ENTER.

Kind Regards !.

okay, thanks.    

 

I still don't see how it applies to degrees and radians but I'll experiment with it when I get home tonight.

 

I seem to be using my HP-50G a lot more lately.  Prime is nice but the more I use it, the less I like it.   I'll never use anything other than HP and RPN but feels good to **bleep** now and then :c)    

 

(In fact, I bought another 50Gs off of ebay as back-up a few weeks ago)

 

Thanks Again,

Deg<=>Rad conversions are normally featured on scientific calcs, but graphings units don't normally have them as a direct button.

 

 

It works fine for me in RPN mode though for me here. I put 90_deg on the stack, followed by 1_rad, and calling CONVERT then converts. How are you trying to use "CONVERT"?

Great, that worked!     

 

I was following the instructions in the article: 

http://h30434.www3.hp.com/t5/Calculators/hp-prime-deg-to-rad-rad-to-deg/m-p/3315481#M4826

 

So I was doing  CONVERT(100_deg, 1_rad)  ENTER

 

Make sense now ... on the stack first like RPN in general.  

 

Thanks for the reply!

 

(Plus the Help on Convert wasn't helpful in RPN mode)

Just like the 48 series, you can embed algebraics by doing ' ' (shift-parenthesis)if you want an equations/expression/command in algebraic form.

 

Be aware that if a command can take variable # of arguments, RPN on prime requires you to specify the count if you are using more then the default lowest number of arguments.

 

For example, ROUND has  an optional 2nd argument. To take 2 arguements from the   stack, you'd do ROUND(2) ENTER to take both. Else ROUND will just take the 1 argument.
