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...

I observe the same behaviour.

AND if you then after 1.677 recall the flashing cursor by pressing the left arrow key, ie rightmost key of third row from top, the answer remains the same false value.
