Bugs in Sandmath44 Rev 7

[fcrvincent]

I found the following bugs in the latest version (June 2025) of Sandmath44 rev 7:

* in the -PB/STS menu :
+ invoking respectively the MEAN and SDEV keys return the values of the standard deviation and the mean instead of the other way around. When I invoke the MEAN SDEV functions directly with XEQ the functions behave as expected; the issue is only when invoked from the Stats/Probs launcher menu.
+ In the second MN (shifted) menu: 0: 1 : N : D : P : W : X : Σ , the following options seem to be assigned to incorrect functions:
0 -> displays EECC, instead of CIRCL
P -> displays CEIL, instead of PL
W -> displays PMEAN, instead of PTWIN
X -> display MTXP instead of PNEXT

* The PTWIN function (looking for the next two prime numbers after X such that P2=P1+2) freezes the HP41CX, that then needs to be reset.
* I also noticed that invoking the HMEAN (Harmonic Mean) function from the -ST/PBS menu returned the same value as the GMEAN (Geometric Mean) and that the AMEAN and PMEAN functions return incorrect values.

UPDATE 28/07/2025:
thanks to Ángel's help, we could resolve all the primary MN menu issues but not the second shifted menu issue above yet): you need to turn off / deactivate the IR-PRINTER module; this works both in the V41 and the 41CX Android emulators.

The whole -PB/STS menu/launcher seems to have function calls issues. Hopefully ÁM will be able to solve this and make his otherwise amazing SandMath package behave as it should.

I did email Ángel Martin and hope that he'll be able to fix this.

UPDATE 01/08/2025

Ángel fixed all the above bugs!

Sandmath works really well.

One just needs to disable the IR-Printer module that seems to interfere with some of Sandmath's functions.

Many thanks to Ángel for keeping the HP41 and all its (software and hardware) emulators at the top of the calculators pack still in 2025, 46 years after its release!
