SandMath Manual - at last!
Message #1 Posted by Ángel Martin on 2 Nov 2012, 2:17 a.m.

After a long delay and numerous startings and postponements, I'm glad to say the SandMath Manual is finally done - and posted at the usual site.

http://hp41.claughan.com/file/SANDMATH_44%20Manual.pdf

It finally got to the point that I didn't remember exactly what was in the module, specially after adding the secondary FAT and the sub-functions - so I needed the manual too!

Won't win a Pulitzer prize but if you're interested in the SandMath then it'll be a great reading. Personally I think it's at the level of the 41Z Manual, hope you also find it interesting.

Cheers, 'AM

Very nice! Looking for rainy days and some idle times in between family and work ...

Thank you, Roger

BTW: is there a typo on page 28 or didn't I get the wit? "2.4.2. RCL Launcher – the Total Rekall." versus "2.4.2. RCL Launcher – the Total Recall."

Thanks Roger - I'm afraid that's an internal wink to the SF series of the same name, you know the Canadian production... call it a poetic license of a teasing mind (writing those manuals is a very dire job! :-)

I like the most:

"Alea jacta est"

"Linear Regression – Let’s not digress"

Cheers Roger

You'd probably have better luck contesting for a Nobel Peace prize. The qualification on that seems to have been exceptionally flexible the past few years... ;-)

Thanks a lot, Angel! The layout and readability of your manuals are perfect!

Now all these powerful functions will never suffer the same fate as other jewels of code that lack documentation - SandMath will never vanish into oblivion!

By the way, may I mention a faulty page numbering in the latest PowerCL manual - something got messed up from page 50 onwards; there are also some typos, if you wish I could send you the references.

Thank you again! Michael

Thanks Michael. Yes I got your remark on the POWERCL manual from the other thread; will eventually fix it but did I already say how hateful MS Word can be? I should´ve use Frame Maker but now it´s too late... but wait, it´s the pdf writer which creates the error so we´re trapped by the Windoze monster again!

Thanks guys, it´s a bit overwhelming response, anyway glad you find it useful. And thanks to Jean-Marc Baillard again for is long-distance runner work expanding the limits of our beloved coconut platform.

Amazing, both the manual and the SandMath functions! Is it possible to have a physical module?

Here is my test of one of the functions:

01 LBL'S
02 2
03 X<>Y
04 Y^X
05 LASTX
06 CHS
07 .5
08 ENTER^
09 SigmaFL#		; SigmaFL$ "LERCH"
10 21                   ;
11 *
12 END

0 XEQ 'S --> 2.000000000 1 R/S --> 5.999999994 2 R/S --> 33.99999999 8 R/S --> 395226754.0 4 R/S --> 3394.000000 5 R/S --> 48966.00010 6 R/S --> 847713.9981 7 R/S --> 17121893.94 3 R/S --> 294.0000000

This evaluates the infinite sum

SUM(k=0,oo,(2*k+1)^n/2^k), where n is a positive integer.
The actual results are integer numbers, but these are quite acceptable.

Best regards,

Gerson.

Edited to fix a typo, as per Ángel's observation below.

Hi Gerson, wonderful little jewel indeed. Now, will you disclose what´s the function programmed under "S" (which BTW I called "GWB" :-)

GWB(n) = 2^n PHI(1/2, -n, 1/2)

where PHI is the Lerch transcendental function...

PS. I see there's a typo in the SandMath manual, where for the stack contents of the output it lists the wrong values. You obviously figured it out!

PPS. typo in line 04 of your program, should be Y^X (or where you using an HP35? :).
