<div class="moz-cite-prefix">I have added a ClpSimplex::cleanPrimalSolution(double

If you are not using trunk then just copy ClpSimplex.?pp from
trunk - or I can send you code.<br>
<br>
Tell me if that works.<br>

<div dir="ltr">Hi,
<div>I'm testing a network flow problem but encounter a
float-point headache. The output is something like the
following:</div>
<div>
<div>"~/MultiCommodityFlowTest.cpp:444: Failure</div>
<div>Value of: linkMap.at(make_pair(0, 3))</div>
<div> Actual: 9.9986685597741598e-13</div>
<div>Expected: 0</div>
</div>
<div>"</div>
<div>Previously, I used glpk and nothing is wrong when using
google unit test(EXPECT_EQ). But Clp still has a couple of
floating-point numbers failures s even I use EXPECT_DOUBLE_EQ
or EXPECT_FLOAT_EQ. </div>
<div>I think the reason is that glpk uses some default
post-processing method to handle the value of variable in
solution, but Clp doesn't have this process. </div>
<div>Is there a way that Clp can round the solution to a
reasonable value rather than the above value? </div>
<div><br>
</div>
<div>Thanks,</div>
<div>Emer</div>

</div>
<div>p.s. Thanks John for the last reply, I have changed the way
to build a constraint matrix from glpk to Clp, and it works
better than the former. </div>
