stack behaviour mismatch
Love this calc, there’s an issue with the stack behaviour, described below, which is supposed to be fixed in the next release as per my comms with the developer.
both 17bx and 19bx are affected.
To reproduce:
- Switch to RPN mode
- Perform the following [1] [Enter] [2] [<-] [3]
Expected stack contents: X=3, Y=1. Actual stack contents: X=3, Y=0, Z=1.
See: P272 (Appendix E: the RPN Stack), “Clearing numbers” section of the HP 17Bii operation manual (linked in the documentation).
I suspect it shouldn’t be pushing zero to the stack, according to the documentation and original 17BII behaviour.

Don’t bother buying this, absolutely no customer support, waiting for this to be fixed since last July, reported a quality issue, nothing happens. Get the RLM-12 instead, it doesn’t have the problem.

Calculations are Precise, but NOT ACCURATE.
The calculator emulates the HP 17Bii calculator well, but it is not accurate. For example: In the >BUSINESS>PERCENTS & MARGINS menu for example: If the [Old Value] is 41.67 and the [New Value] is 80.00, the [% Change] is 91.98, but the calculator inaccurately registers the value as 92.00. Also in the Help section, the instruction booklet which is the exact copy of the Hewlett Packard 17Bii calculator, is not indexed with a FIND search feature.

Response from developer
We couldn't reproduce the inaccuracy you mentioned. Please be sure that the #PD value is set to 1.0 and perform the calculation of %CHG.
