is_infinite

Checks if the provided absolute of the value is larger or equal to "infinite".

unsigned char is_infinite(lprec *lp, REAL value);

Return Value

is_infinite returns TRUE if the value is equal or larger to "infinite".

Parameters

lp

Pointer to previously created lp model. See return value of make_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI

value

The value to check against "infinite".

Remarks

Note that the absolute of the provided value is checked against the value set by set_infinite.

Example

#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"

int main(void)
{
  lprec *lp;
  unsigned char infinite;

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

  infinite = is_infinite(lp, 1.0e31); /* will return TRUE */

  delete_lp(lp);
  return(0);
}
