is_integerscaling

Returns if integer scaling is active.

unsigned char is_integerscaling(lprec *lp);

Return Value

is_integerscaling returns if integer scaling is active (SCALE_INTEGERS set in get_scalelimit)

Parameters

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

Remarks

The is_integerscaling function returns if integer scaling is active (SCALE_INTEGERS set in get_scalelimit). By default integers are not scaled. set_scaling must be called to active this feature.

Example

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

int main(void)
{
  lprec *lp;
  int integerscaling;

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

  integerscaling = is_integerscaling(lp); /* Will return 0 */

  delete_lp(lp);
  return(0);
}
