WP 34S - indirect addressing issue

[Gerson W. Barbosa]

I've noticed indirect addressing doesn't work when the fractional part of the index is equal or greater than 0.5. Of course, by definition indices are integer numbers. However, as a convenience, HP calculators accept non-integer number as indices for indirect addressing and just ignore the fractional part. Is this a WP 34S bug or a feature? Thanks!

It seems to be working:

    1 STO 01

    2 STO 02

    1.75 RCL-> X

Returns 1 as it should.

In other words, I'm not understanding the problem here. Any chance of a step by step reproduction please?

Returns 2 in version 2.2 build 1975 (Emulator).

Also,

99 STO 99

99.99 RCL-> X

returns 99.99

You are correct. I tested in v3 which this is all working happily.

The proper solution is to upgrade ;-)

I've committed a fix.
I don't know when the next v2.2 build will occur.

As soon as I get a working USB-to-serial adapter. Or a new USB cable, if it is ever released :-)

I could do one this week if someone can point me to the fix. I've yet to patch to serial port fix into 2.2 as well.

I committed the fix in the 2.2 branch.

I can confirm an error for version 2.2 1789 (emulator) where this returns 2.

The same works fine in version 3.0 2289 (also emulated). Here it returns 1, as it should.

I was having trouble in a program that worked on the HP-42S but would not work on my outdated WP 34S.

Mine was flashed last July. Just received Eric's overlays (very nice on the former 20b!). A suitable USB-to-serial converter is still missing though.

Cheers,

Gerson.
