set_epsb

# set_epsb Specifies the value that is used as a tolerance for the Right Hand Side (RHS) to determine whether a value should be considered as 0. void set_epsb(lprec *lp, REAL epsb); Return Value set_epsb has no return value. Parameters lp Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI epsb The value that is used as a tolerance for the Right Hand Side (RHS) to determine whether a value should be considered as 0. Remarks The set_epsb function specifies the value that is used as a tolerance for the Right Hand Side (RHS) to determine whether a value should be considered as 0. Floating-point calculations always result in loss of precision and rounding errors. Therefore a very small value (example 1e-99) could be the result of such errors and should be considered as 0 for the algorithm. epsb specifies the tolerance to determine if a RHS value should be considered as 0. If abs(value) is less than this epsb value in the RHS, it is considered as 0. The default epsb value is 1.0e-10 Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;

      /* Create a new LP model */
      lp = make_lp(0, 0);
      if(lp == NULL) {
        fprintf(stderr, "Unable to create new LP model\n");
        return(1);
      }

      set_epsb(lp, 1.0e-9); /* sets epsb to 1e-9 */

      delete_lp(lp);
      return(0);
    }
