HP 50g Error and user Manual Error

In the explanation of the SOLVE environment, they use the equation e^x - sin(pi*x/3)=0.

They show a solution (a root) of ~4.5E-02. This is actually an extremum, (f(x)=~.9989) which the Prime correctly shows in it's solve app. I confirmed that the HP 50g handheld produces this error. ...

[emphasis added]

Yes, the manual is in error in stating that it is a solution, but no, the 50g itself is not in error, because if you press the INFO menu key, you'll see that the returned value is an "Extremum". After pressing SOLVE on the 50g, you should always press INFO.
