Possible error in on-calculator help.

This is from a different thread (the one that spawned this thread), but I thought it was pertinent to the discussion.

Inefficient perhaps, but it also seems to have much less room for misinterpretation and confusion. If complex mode behaved like it did on the hp49, but you still left the complex solvers (csolve() cfactor() etc) or a function that instructed the calculator to evaluate with complex output for when you explicitly need complex answers, the inefficiency could be partially abated.

Edit:

If a generalized function for forcing complex output (or individual functions for everything that you would need in the complex domain) were available, having a setting for complex output would be redundant.
