RE: Max value of 3 variables
Max() should do it if you're not going to eventually have more values. Think it can only take 2 values so nest them like max(max(no1, no2), no3) If its going to be more... just loop them, if the currnent value is larger than the previous, set it to the max... cfset max = 0 cfloop list=#numbers# index=i cfif i gt max cfset max = i /cfif /cfloop -Original Message- From: G [mailto:[EMAIL PROTECTED] Sent: Friday, April 15, 2005 8:58 AM To: CF-Talk Subject: Max value of 3 variables Got three variables passed into me, all are decimal values.

Re: Max value of 3 variables
Calvin Ward wrote: For flexibility, how about this: ListFirst(ListSort(numbers,'numeric')) 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 K. ~| Logware (www.logware.us): a new and convenient web-based time tracking application.

No, it doesn't touch the list except to sort it, and then return the first value in the list. If it's just three numbers, then Max(Max(a, b), c) is fine, but as the saying goes, two is an impossible number[1]: it's worth generalising this to cope with any number of values, which is what everybody was doing.
