[WP34s] Unexpected results in fraction mode

[code] keys display
[.] 1 [.] 6
[ENTER] 1/6
[1/x] 5 1/1
[DECM] 6 // actually 5,999999...9

For reference only, here's what the Prime's fraction button yields in Home view (rev 6030 only):

FIX 11 mode: 400,000,000,001 / 66,666,666,667 (or 5 + 66,666,666,666 / 66,666,666,667).
This is the simplest fraction that rounds to 5.99999999999.
I think Prime is the only calculator in the world that finds this result, due to its superior fraction algorithm.

STD or FIX 10 (or less): 6.
As expected.
