is there a filter to fix floating point precision?

[Jacob G]

I'd like to fix floating point precision (using rounding if necessary), as in:

• 3 => "3.00"
• 2.4 => "2.40"
• 2.45 => "2.45"
• 2.455 => "2.46"
• 2.454 => "2.45"

The rounding filter does not fix precision, rather it's a max precision, i.e.,:

• 2.4 | round(2) => 2.4

Is there such a filter in nunjucks? In jinja, the format filter could be used for that, but that filter uses native python formatting.

This'll do it:

installFixed: function () {

   function fixedFilter (number, digits) {

      return number.toFixed(digits);
   }

   this.getEnv().addFilter('fixed', fixedFilter);
},

Try this directly, without any custom filters:

{{ ( numberToDisplay|float ).toFixed(2)}}
