Follow-up Comment #1, bug #55682 (project octave):
What trivial problems make the guys at Mathworks feel the need to complexify
their API... If you only need this to solve a given problem right now, just
use
Y=round(X*10^N)/10^N;
But beware that these are then floating-point numbers, that is, if you get
let's say 1.3 in this way and 2.7, it is not guaranteed that their sum is
equal to a corresponding expression of 4.0 (different from proper rounding,
which gives you integer-valued doubles that conform to exact arithmetics as
long as you do not exceed bitmax()).
