<div>Hi Rick,</div>
<div><br>
</div>
<div>I am running into an issue where I have some repeat values.  Is there a way to add a precision level adjustment during the qsort algorithm? </div>

<div>Hi Jonathan -- yes, qsort() takes a double, or more generally a "numeric" type.</div>

Hello NCL-Talk,<br>
<br>
Does qsort operate at double precision?<br>
I am trying to resolve my stat_dispersion issue by isolating the problem...<br>
