Easy Display of Dollars

You know those stupid little things you come accross after years in the profession, that make 
you say "Golly, if I'd just known that 3 or 4 years ago, it would have saved a ton of work!" 
This is one of them. 

what is the easiest way to express a formatted dollar amount? 

<? echo(sprintf("\$ %.2f",$amount)); ?> 

Here is a more robust function: 

<? function dispdollars($amount, $style) 
{ 
   //slam it! 
   $amount=doubleval($amount); 

   if ($amount>=0) 
      echo(sprintf("\$ %.2f",$amount); 
   else 
      if ($style==0) 
         echo(sprintf("-\$ %.2f",-$amount); 
      else 
         echo("<font color=red>".sprintf("\$ %.2f",-$amount)."</font>"); 

} 

Example  : 

<html> 
<? 
   $amount=1.2345; 

   echo("the value $amount expressed in dollars is ".dispdollars($amount)."."); 

?> 

</html>
