<p class="MsoNormal">Indeed this would probably break some code. We should carefully check the exist() usage within Scilab to ensure the output value is not passed to macros/gateways checking for a “double†datatype. Code using exists() output value as index
or as condition might not be affected.<o:p></o:p></p>

<p>Hello Federico,<o:p></o:p></p>
<p>I agree with you that this would make more sense.<br>
Could such a change be implemented for a point release?<br>
I assume it would introduce some bugs in existing code relying on the (unusual) double output...<o:p></o:p></p>

Dear all,<br>
<br>
<span style="font-family:"Courier New"">I had already mentioned this a while ago (<a href="http://mailinglists.scilab.org/Scilab-users-exists-yields-double-tt4039853.html">http://mailinglists.scilab.org/Scilab-users-exists-yields-double-tt4039853.html</a>),
but as I guess we are in the update season, it would be good opportunity to fix this (if there isn't strong opposition, or a good reason for this behavior, of course).<br>
<br>
I'm referring to the fact that the function exists() should by nature yield a Boolean result such as T or F. However, it yields 1 or 0. While this is not a big deal, similar functions performing a binary decision on their arguments, such as isreal(), isvector(),
isfile() and many others, yield Boolean results. <br>
<br>
Regards,<br>
<br>
