23akari u seem to fogot to remove those points wich dont satisfy eg : [0,1] [3]
[x]=[2y]
(From kalyan's post I realized that somehow this type has not been discussed!)

62no kalyan.. try to take some point on your graph and see if it actually satisfies!
106[x] = [|2y|]
=> x ≥ 0 (and the graph is symmetric about x-axis)
draw the graph of [x] = [2y] (for x≥0) and then reflect the graph about x-axis
