<h1><a href="https://projects.ecoinformatics.org/ecoinfo/issues/6439">Bug #6439: Double rounding fails in some cases while evaluating Expressions</a></h1>
<ul>
<li>Author: Owsiak Michal</li>
<li>Status: New</li>
<li>Priority: Urgent</li>
<li>Assignee: Derik Barseghian</li>
<li>Category: actors</li>
<li>Target version: 2.3.0</li>
<li>Bugzilla-Id: </li>
</ul>
<p>It seems that addition of doubles can produce values slightly different than they should to be.</p>
<p>Please take a look at attached workflow (simple_error.xml).</p>
<p>Condition that should be satisfied to escape the loop is: 1.7 > 1.5 + 0.1</p>
<p>However, loop is interrupted sooner, because of incorrect calculation of doubles. Value of "p" is set to: 1.6000000000000003</p>
<p>This, of course, makes it impossible to use doubles as check points for the loops.</p>
<p>However, it seems that casting to string and back works fine (take a look at second workflow - simple.xml)</p>
<p>Cheers</p>
<p>Michal</p>
