How to use sprintf in Twig to format a number?

Question

I need to format a number like this:

sprintf(\"%05d\",$lineNumber)

But I\'m inside a Symfony2 Twig template. So what can I do?

Answer 1

If i was 4 before, then after adding this to your Twig template:

"%02d"|format(i)

...it will become 04.

Answer 2

Twig provides lots of filters, take a look at format and number_format.
