Thank you, Bob.
Following your pointer, I did some testing.

Indeed, in this model, if the 5/4 selector is set to 4 decimal places, I get these answers:
1/3 = 0.3333 (5th decimal digit value below 5, so round down)
1/6 = 0.1667 (5th decimal digit value equal or above 5, so round up)

And this is what I have learn at the engineering technical school in the 70's, but we didn't call it 5/4, so I was not associating it with the rounding rules at all.
