You are kind of proving my larger point that the implementation of the complex number formats standard and functions is screwy. Certain formats and functions/buttons works in some modes and in others not. This is confusing the user constantly... 1. There is a [∡] button and it works as it should in Home but not in CAS (super frustrating - forcing people to implement their own conversion functions - see various attempts in the http://www.hpmuseum.org/forum/forum-15.html ). 2. Some complex number formats work in RPN but not in CAS or textbook (home), e.g. 2i4 is interpreted different. It short it’s a mess. An engineer (EE, CE in particular), who needs to constantly move back and forth between polar and cartesian coordinates (and calc/pre calc high school student too for that matter), should be able to expect the calculator to accept the same number formats and operate the same regardless of he/she is using RPN, textbook format (home) or CAS. Wouldn't it be great if we could standardize across all three, e.g. 4i3, 3∡(pi/2) works everywhere - simple notation that saves key strokes. You can then do things like (4i3) * (3∡(pi/2)) in Textbook (Home) and CAS or in RPN: 4i3 <enter> 3∡(pi/2) <enter> * <enter> and the expected results |
