Precision

The number entered here determines how closely the calculated values of the constraint left hand sides must match the right hand sides in order for the constraint to be satisfied. Recall from Elements of Solver Models that a constraint is satisfied if the relation it represents is true within a small tolerance; the Precision value is that tolerance. With the default setting of 1.0E-6 (0.000001), a calculated left hand side of -1.0E-7 would satisfy a contraint such as A1 >= 0.
