If we were talking about a lower-level language, I'd warn against that
way of doing it. On average, ListSort() takes O(nlogn) to sort a list,
whereas scanning the list with <cfloop> as below will be done in O(n)
time, which is faster. The only advantage that using ListSort() has is
that it's precompiled into Java.
Come to think of it, a linear scan will still be faster regardless,
unless you're dealing with CF5 or below.
The best and safest way to scan an unsorted list for the maximum number
would be:
<!---
Using the first element as our default max ensures that if the
list contains only negative numbers, it will still work properly.
This is my one improvement over Ewok's method.
--->
<cfset max = ListFirst(numbers)>
<cfloop index="i" list="#numbers#">
<cfif i gt max>
<cfset max = i>
</cfif>
</cfloop>
