[FIXED] Twig - How to check if variable is a number / integer

Issue

How to check if variable is a number, integer or float? I can't find anything about this. Making project in Symfony 3.

Solution

At last found something. One of the answers from: https://craftcms.stackexchange.com/questions/932/how-to-check-variable-type

{# Match integer #}
{% if var matches '/^\\d+$/' %}
{% endif %}

{# Match floating point number #}
{% if var matches '/^[-+]?[0-9]*\\.?[0-9]+$/' %}
{% endif %}
