[FIXED] How to use float filter to show just two digits after decimal point?

Issue

I am using Flask/Jinja2 template to show a number using |float filter.

Here is my code

{% set proc_err = nb_err|length / sum * 100 %}
({{proc_err|float}}%)

Output is a bit awkward:

17/189 (8.99470899471%)

I am looking for a way to make the places after dot limited to a number e.g. 2.

Desired output:

17/189 (8.99%)

Solution

It turns to be quite simple:

My code:

{% set proc_err = nb_err|length / sum * 100 %}
({{proc_err|float}}%)

Can be changed a bit with:

{% set proc_err = nb_err|length / sum * 100 %}
({{'%0.2f' % proc_err|float}}%)

or using format:

({{'%0.2f'| format(proc_err|float)}}%)

Reference can be found here on jinja2 github issue 70
