Jinja2 round filter not rounding

python flask jinja2 template-engine

You can put parens around the value that you want to round. (This works for division as well, contrary to what @sobri wrote.)

{{ (deet.value/100)|round }}

NOTE: round returns a float so if you really want the int you have to pass the value through that filter as well.

{{ (deet.value/100)|round|int }}

python flask jinja2 template-engine

Didn't realize the filter operator had precedence over multiplication!

Following up on bernie's comment, I switched

{{ deet.value*100|round(1) }}

{{ 100*deet.value|round(1) }}

which solved the problem. I agree the processing should happen in the code elsewhere, and that would be better practice.

python flask jinja2 template-engine

Try this

{{ (deet.value*100)|round(1) }}

If we didn't put parenthesis, round will do only to 100 not to the result.
