I want to use {% if %} in a node.html.twig, but it doesn't work.

I am using this code.

{% if content.field_number == 0 %}
  zero
{% else %}
  one
{% endif %}

It always print one.

The following code always print zero.

{% if content.field_number %}
  zero
{% else %}
  one
{% endif %}

What code should I use to zero when the field contains zero?

content.field_number is the rendered output and the value of the field is somewhere inside the render array, for example in a #markup. But this will change whenever someone reconfigures the view mode.

It is better to use the node object in this case, because the field value will be available for all view mode configurations:

{% if node.field_number.value %}
  not zero
{% else %}
  zero
{% endif %}
