solver gives -3.04544793089 Sign Reversal, with 0: - 4.50061385902E-2 Extremum. It's up to you to decide which answer to use.

How do you get it to show the "Sign Reversal" or "Extremum" messages? I'm using the NUM.SLV menu, [↱] [7], and I'm getting the same numbers as you, but no messages explaining what those numbers are.

EDIT: Oh, wait, never mind. Press [INFO]. Of course.
