Precision in computations c++ Cplex
<p>I implemented my mathematical model using Ilog Cplex with c++. Most of my decision variables have fractional values in the optimal solutions. Some of them are very small that cplex outputs them as 0. Is there a way to increase the precision so that I can still see the values of such variables?</p>

<p>Also, when I use <code>cplex.getBestObjValue()</code>, it gives me "-Inf". (This is a maximization problem.)</p>
