Display number output field as whole number

I've found that by far the easiest/simplest way to achieve this is to just use the FLOOR() Visualforce function:

<apex:outputText value="{!FLOOR(sObject.Number__c)}"/>

would formatting do the trick?

   <apex:outputText value="{0,number,#,##0}">$    
       <apex:param value="{!soBject__c.Number__c}"/>
    </apex:outputText>
