<p>Hi,</p>
<p>Most LP based solvers use limited precision (double) to compute
solutions. Thus, you can expect some "trash" to appear after, say,
the 9th decimal place. <br>
</p>
<p>Gurobi has a special mode where quad precision is used.</p>
<p>GLPK has an exact mode but I think that it only applied to LP (no
MIP).<br>

<div> I am using MILP. During solving, i want the
decimal variable precession to be rounded to limited places.
(some times solver returns variables values of factor e^-12).
Is there a way to limit it. </div>
