What you're looking for is sprintf() though I suspect you know that  
already from your comment below. Ie:

	sprintf( "%0.02f", 234.2342342)

You deride this as "string manipulation" though in effect as soon as  
you display the number that's what you're doing, no matter where or  
why you want to display it. The number only exists as a true float as  
long as you don't look at it; as soon as you do, you've forced it to  
achieve stringness.

Makes sense?
