Is it possible to format a number to 2 decimal places with Smarty PHP

问题

Is it possible to format a number to 2 decimal places with Smarty PHP?

Thanks.

回答1:

string_format accepts sprintf formatting options:

{$number|string_format:"%.2f"}

回答2:

{$number|number_format:2} is what you want

回答3:

{$number|round:"2"} also works

回答4:

To display 2 instead of 2.00 you can use : replace in Smarty PHP

See below example -

$number = 2.00

{$number|replace:'.00':''}

Output :- 2 

Hope this helps.
