Personally, Id suggest one regular one (not using NPV) & one using NPV.

Willy is interested as he plans to do an update soon.

Bob,

Your suggestion is ok. At first, I didn't see the point of including the program using NPV, as it is meant for the real HP-38C, but it makes sense as some RPN-38 CX user have the real thing and occasionally might run such program on their vintage calculators. I suspect you are my only customer, though :-)

So the programs I would choose are the one in post #23, written specifically for RPN-38 CX, and the one in post #29 with the modified constants R4 through R6 and modified steps 71 through 74 as listed in post #31. RPN-38 CX is also a great development tool. Thanks, Willy, for its editing capabilities!

If RPN-32 CE is also going to be updated, I would suggest the addition of the conditional tests x<=y and x=0. I haven't explored it yet, but I so far I've seen x=y, x<y and x>y only.

Again, thank you for your suggestions and ideas.

Gerson.

Gerson, your Trig program of 4 April is included as a sample program in the recent update to RPN-38 CX. It's listed as "Trig Functions (High-Precision)." Constants are automatically loaded if you select "Import w/Regs (all)." You may have to press either Add or Reload Sample Programs the first time after updating the app. Also, your issues with both the 38 & 32 apps should have been addressed with this latest update. RCL arithmetic for Last X was added. Also constants are now saved when exporting to Dropbox and (I think) email.

Your program seems to be running perfectly. For ASIN, ACOS, & ATAN, GOTO 35, 46, & 54.
