title: Smarty template with comma and decimal
body: <p>I have to calculate a smarty variable with 23,50 Euro e.g if variable = 100 than {$variable+23,50} it should be 123,50 Euro. In template the variable accepts only {$variable+23.50} which gives me 24,50. the same with 1000 Euro {$variable+23,50} I need a value 1.023,50</p>
