Is there any way to detect data type of value? #1392

I have a requirements to use "float" and perform some calculation. But When input is alphanumeric value it is throwing an error. So I want to put some check, like If value is numeric than only perform calculation.

Can anyone help me with this using nunjuck ?

You can add custom test

environment.addTest('float', (value) => Number.isInteger(value) && value % 1 !== 0);

And use it like

{% if value is float %}
