Try entering 5, Input, 1.677, Math, Down, Down, Input, Down, Down - I then see 9.22...., ie the correct answer.

Now try the same with = after the 1.677 - I now get 8.706...., ie the wrong answer.

OS Version is still 4 5 2010 2.

Can anyone corroborate behaviour or say it's been fixed in later versions?

I'm pleased to say that, by hook or by crook & with the assistance of members of the forum, I now have an HP 30b version 5 4 2012 5.

Contrary to member John Smitherman's experience, on attempting the quoted procedure the calculator does NOT return the correct result consistently.

In fact the machine now prefers to report "Error:Invalid Input Student", a questionable improvement.

Whatever bugs may have been corrected remains a mystery to me.
