You should note, that if your original model was an LP the new model is a MIP model, and the solution time could be much larger. Also note, the default upper bound on an integer variable is 100 which will translate into | You should note, that if your original model was an LP the new model is a MIP model, and the solution time could be much larger.

If you have larger x-values you can increase the upper bound on y, but rounding for large X-values does not make much sense. | + | an upper bound on x of 1+0.25*100 = 26.
