Visualforce currency euro

Question

I need to display currency. This field is Roll-up summary of formula fields with return type 'Number'

<apex:outputText value="{0, number, currency}">
    <apex:param value="{!Invoice.Amount__c}" />
</apex:outputText>  

But this shows amount like this in html: $150.00

I need there to be euro instead of dollar.

Answer 1

<apex:outputText value="{0, number, ###,###,###,##0.00}">
    <apex:param value="{!Invoice.Amount__c}" />
</apex:outputText>&euro; 

This worked

& + euro; is for €

Answer 2

<apex:outputText rendered="{!IF(ISNULL(Invoice.Amount__c),false,true)}" value="€ "/>                     
<apex:outputField value="{!Invoice.Amount__c}"/> 

It works perfect for me for large number values.
