<p class="indent">The value that is used as a tolerance for the Right Hand Side

<p class="label"><b>Remarks</b></p>
<p>The <b>set_epsb</b> 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.<br>
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. <i>epsb</i> specifies
the tolerance to determine if a RHS value should be considered as 0. If
abs(value) is less than this <i>epsb</i> value in the RHS, it is considered as
0.<br>
The default <i>epsb</i> value is 1.0e-10

<p class="label"><b>Example</b></p>
<pre><code>#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);
}
