Happy New Year
Message #1 Posted by Matthias Wehrli on 31 Dec 2007, 5:06 p.m.

So, in Switzerland we have only 55 minutes to go... I will go to the firework here in Basel with my wife and our friends.

I wish you all the best for the new year ... ... and certainly a lot of good deals with me ;)

Allen,

Do I need an HP-16C?

Hi, Trent --

Quote:
Do I need an HP-16C (to decode "#7D8h")?

To enter "#7D8h" exactly as written requires an HP-48/49/50. "#7D8" in HEX mode suffices on an HP-28.

On an HP-16C, HP-33s, or any scientific Pioneer-series model except the HP-21S, enter "7D8" in HEX mode.

Then, of course, convert to decimal integer.


On the HP-35s, "7D8h" is required, but the BASE functionality is a hassle, so I don't enthusiastically recommend using it. But, here's the sequence anyway:

[BASE 2] 7 [sqrt] 8 [BASE 6] [BASE 1]  

"BASE 2" enters HEX mode so that the digits to be entered will not be converted from another mode to hexadecimal upon subsequently entering HEX mode.

"sqrt" corresponds to the key for entering hexadecimal D (the third row is the only row providing six keys for hexadecimal A-F).

"BASE 6" appends the mandatory "h" code for defining a hexadecimal input.

"BASE 1" converts to decimal mode.

Hi, Les --

We old Sperry/Univac mainframe programmers from the 1980's understand that one, too.

I am at a complete loss to think of the use of such a mode on a calculator.

Almost as irrelevant as my never submitted IOCCC entry that included an option for base-9 output.

Hello Walter,

You're fully right: my pseudo-latin is definitely awful !

In french, we call this "latin de cuisine" ie "kitchen latin" which is a way to name a degraded and incorrect latin often used pedantically (such as in my post :-)

However my best wishes to all in french should be correct :-)

Cheers

Etienne

The base conversions are particularly easy on the HP-27S.

From decimal: Key in the number, then [BASE = Shift 4] to get a menu.

Pick the soft key for the desired base ([HEX], [OCT], [BIN]), and you're done.

To decimal: First choose the starting base from the [BASE] menu.

Choosing HEX converts the 6 soft keys to the extra digit keys A-F; this is so much better than the new 35S where the letters could have matched up to the corresponding alpha keys, but don't.

Key the number. and [EXIT] takes you out of the menu with the decimal equivalent displayed.

Ken --

Yes, indeed, base-integer conversions work fundamentally the same way on "any scientific Pioneer-series model except the HP-21S", as I'd alluded. The HP-27S functionality is exactly the same as that of the HP-42S, which shares the same display unit.

I agree that the Pioneer implementation is well-conceived and easy to use. Here's a link:

Thanks for the link. I read with interest until it degenerated into a semantic argument. It's true that I've been too lazy to RTFM so I didn't know the word size on the Pioneers. One of the main points of that thread for me was that knowing the word size of the machine you're using can be very important.

I must search the archives more, too. Obviously a gold mine of useful stuff.
