Unlike an error, a warning doesn't abort the currently running program. A simple example of a warning is when a number is divided by zero. In this case Octave will issue a warning and assign the value <code>Inf</code> to the result. <pre class="example"> a = 1/0 -| warning: division by zero ⇒ a = Inf </pre> <ul class="menu"> <li><a accesskey="1" href="Issuing-Warnings.html#Issuing-Warnings">Issuing Warnings</a> <li><a accesskey="2" href="Enabling-and-Disabling-Warnings.html#Enabling-and-Disabling-Warnings">Enabling and Disabling Warnings</a> </ul> </body></html>
