<p>In CoinMpsIO.cpp tinyElement is hard coded as 1.0e-14.<br>
<br>
In Clp, when primal or dual is entered all values < smallElement_ are treated as zero. This has default value of 1.0e-20 and can be changed by setSmallElement.<br>
<br>
If there was a general feeling that it would be useful to have a function like ekk_setRtolmps then it would be easy to add smallElement_ to CoinMpsIO.?pp and let Clp use max of ClpModel::smallElement_ and CoinMpsIO::smallElement_ when reading an Mps file.<br>

<font size="4">Hi,</font><br>
<font size="4"> </font><br>
<font size="4">Is there setting mps tolerance function in CLP, I know there is one in OSL as following</font><br>
<font size="4"> // Set MPS file tolerance so that very small numbers<br>
// are considered zero.<br>
ekk_setRtolmps(myModel, mpsTolerance);</font><br>
<font size="4">Thanks,</font><br>
