On printing floating-point values printf performs appropriate rounding, for example, 0.99999999231 being printed with 6 decimal places looks like 1.00000 . Most probably the value reported by glp_get_col_prim is a bit (i.e. within a tolerance) less than 1, so on printing it you see 1 while on casting it to int you get 0, because converting double to int assumes rounding toward zero. To get correctly rounded result you should write (int)(x + 0.5) rather than (int)(x). _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
