<h3>ArrayMin Example</h3>
<p>This example uses ArrayMin to find the smallest number in an array.<br></p>
<!--- After checking whether the form has been submitted, this code creates an
array and assigns the form fields to the first two elements. ----->
<cfif IsDefined("FORM.submit")>
   <cfset myNumberArray = ArrayNew(1)>
   <cfset myNumberArray[1] = FORM.number1>
   <cfset myNumberArray[2] = FORM.number2>
      
   <cfif Form.Submit is "Minimum Value">   
      <!--- use ArrayMin to find the smallest number in the array --->
      <p>The smallest number that you entered is
      <cfoutput>#ArrayMin(myNumberArray)#.</cfoutput>
   </cfif>   
</cfif>   
<!---- The following form provides two numeric fields that are compared when the
form is submitted. ----->
<form action = "arraymin.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 = "Minimum Value">
