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 can corroborate, with SW Version 4 5 2010 1

In fact, I only get the correct value if I go to math menu just after entering the 1.667 value, pressing nothing else. If I do any other key presses (INPUT, =, 4 "roll downs" or 2 "swaps") I get 8.706...
