RE: WP34S Rectangular/Polar (Suggested Change)
Pardon me parachuting into a thread, but...
I never understood why complex value isn't always stored as P internally, with >R and >P only being different by a display flag (and input handling), in cases such as this. In other words, is there a technical reason why both >P and >R don't assemble a polar vector internally from X: and Y: (taken literally, as polar, or calculated from rectangular coordinates, based on the key), then >R sets a flag that triggers conversion to rectangular on display, while >P does not? Sure, doing all calculations in polar (internally) even when user wants them (and sees them) in R will accumulate an error, but isn't an error in the Nth decimal place of the mantissa better than a whole k*pi of error?
