Yesterday I saw a post on the Brazilian ColdFusion list CF-BRASIL where a colleague was asking for any function to convert a value into the Brazilian currency “Reais” in the form of text. I remembered that I wrote a custom tag for that in 2002, but it had some problems writing the cents. Well, I worked on it tonight and accomplished to make a component which I called “rpMoneyBrExt.cfc“. Since I’m tired, I didn’t test it thoroughly, but I made it sure to write the cents correctly now. So if you want to use, troubleshoot or modify it, be my guest, just send me your changes and keep my copyright notice. Download the component and a test template rpMoneyExtBr

Here is how you call the component:{code type=coldfusion}
<cfscript>
amt = "420392235497.32";
money = createObject("component", "rpMoneyExtBr");
writeOutput("<br>" & amt);
writeOutput("<br>" & money.convert(amt));
</cfscript>{/code}
Here is the component:{code type=coldfusion}
<cfcomponent displayname="rpMoneyBrExt" hint="Converts a value into a written currency text" output="false">
<cfprocessingdirective pageencoding="utf-8" />
<cfscript>
