<div class="moz-cite-prefix">Hello,<br>
<br>
from my point of view this is a very bad idea.<br>
In a simulation you should only use ns-3 based random variables.<br>
<br>
See: <a class="moz-txt-link-freetext" href="https://www.nsnam.org/docs/manual/html/random-variables.html">https://www.nsnam.org/docs/manual/html/random-variables.html</a><br>
<br>
This guarantees 100% reproducibility. <br>

Greetings,<br>

You have to seed it.<br>

Put this code at the beginning of you code.<br>

<div>but when I want to display the value of a </div>
