I think he meant something like this:
add.w d0,dn ; d0 contains a constant 0.16 fixed point value less than one
bcs move_to_right
However this feel very inefficient, using addx and reversed int/frac part would certainly be more usable here.
As ggn said, rounding can be done with just pre-adding the 0.5 value to your d0.
