Yes, this may cause incorrect results. Imagine that x = 0.999999 due to round-off errors in the simplex solver. Then (int)x -> 0 (incorrect) while (int)(x + .5) -> 1 (correct) _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
