Im trying to format numbers with thousands separator Smarty.

or you can use php function inside smarty, this is for number_format, you can use other php function too :)

PHP : number_format($number, 2, '.', ',');

SMARTY :
{$number|number_format:2:".":","}

---

or just in smarty use {$var|number_format:0}

Try to use string_format, it uses sprintf to format your string.
