<h3>ArrayMax Example</h3>
<p>This example uses ArrayMax to find the largest number in an array.<br> </p>
<!--- After checking whether the form has been submitted, the code creates an 
array
and assigns the form fields to the first two elements in the array. ---->
<cfif IsDefined("FORM.submit")>
   <cfset myNumberArray = ArrayNew(1)>
   <cfset myNumberArray[1] = number1>
   <cfset myNumberArray[2] = number2>
   <cfif Form.Submit is "Maximum Value">   
      <!--- use ArrayMax to find the largest number in the array --->
      <p>The largest number that you entered is
      <cfoutput>#ArrayMax(myNumberArray)#.</cfoutput>
   </cfif>   
</cfif>   
<!---- The following form provides two numeric fields that are compared when 
the
form is submitted. --->
<form action = "arraymax.cfm">
<input type = "hidden" name = "number1_Float">
<input type = "hidden" name = "number2_Float">
<input type = "text" name = "number1"><br>
<input type = "text" name = "number2"><br>
<input type = "submit" name = "submit" value = "Maximum Value">
</form>
