The answer was down voted. I almost expected such a reaction.

The rounding I promote is called 'stochastic rounding'.

    If the fractional part of y is .5, choose q randomly among y + 0.5
    and y - 0.5, with equal probability.
   
It is an unbiased tie-breaking rule which is essentially free of
overall bias; but it is also fair among even and odd q values!

In many numerical applications this is the best strategy you can choose.

'map(op, L)' is perfect for me and my old Maple version! Thank you!
