Hi, <br><br>Upgrading my version of matplotlib, I encountered a really weird problem. <br><br>Before, with the 0.99.1.1 version of matplotlib, I could calculate (in the calculator), <br>e_interne*(1.4-1)/286.95 without any problem. <br>
<br>After upgrading, the result of this calculation is zero everywhere... <br><br>Is there any explanation for this ?<br>
