The Comparison operators: <code class="computeroutput"><span class="special">==</span></code>,
|
|
|
|
|
|
<code class="computeroutput"><span class="special">!=</span></code>, <code class="computeroutput"><span class="special"><</span></code>,
|
|
|
|
|
|
<code class="computeroutput"><span class="special"><=</span></code>, <code class="computeroutput"><span class="special">>=</span></code>
|
|
|
|
|
|
and <code class="computeroutput"><span class="special">>=</span></code> work generically
|
2006-08-22 15:57:13 +00:00
|
|
|
|
on all Fusion sequences. Comparison operators are "short- circuited":
|
|
|
|
|
|
elementary comparisons start from the first elements and are performed
|
|
|
|
|
|
only until the result is clear.
