RE: HP 10bii+ Margin/Markup bug
I have a 17BII too, and found other issues with how these subjects are implemented on various HP calculators. For example:
Code:
HP 17BII           HP 200LX, HP CALC, Bus%   HP 10BII+
=================  =======================   ==============
OLD NEW %CH        OLD NEW %CHG              MU CST PRC MAR
TOTAL PART %T      TOTAL PART %TOTAL
COST PRICE M%C     
COST PRICE M%P     More (separate screen)
                   =======================  
                   COST PRICE MARKUP MARGIN

Solver no L(),G()  Solver has L(),G()
None of the above will solve for Margin given Markup or vice versa.

The 17BII "OLD NEW %CH" and "COST PRICE M%C" are the same math with different variable names.

The 200LX "OLD NEW %CHG" and "COST PRICE MARKUP" are the same math with different variable names.

The 200LX Solver has function L() (Let variable equal expression, needed for my Solver function earlier in this thread) but the 17bII is missing it.

The 17BII "M%C" ("MARKUP%C" when solved) and "M%P" ("MARKUP%P" when solved) should be PROFIT (price - cost) as a percentage of Cost or Price, not MARKUP as a percentage of Cost or Price. The wrong word is used.

The 10bII+ MAR key can mean either MARkup or MARgin, a confusing choice of a key legend.

The 200LX variable order (COST PRICE MARKUP MARGIN) seems more logical than the 10bII+ (MarkUp CoST PRiCe MARgin).

3/31/21 Edit: REVENUE changed to PROFIT (error correction).
