    {{ p1 + p2 }}
{% endmacro %}
{% macro p_int(p1, p2, op = 1) %}
    {% set p1 = p1|trim|split('')|reverse %}
    {% set ret = 0 %}
    {% for d in p1 %}
        {% set n = loop.index0 %}
        {% set ret = ret + d*10**n %}
    {% endfor %}
    {{ret + op*p2}}
{% endmacro %}
{% set retval %}
{{_self.myfunc(10)}}
{% endset %}

{% set retval2 %}
{{_self.p_int(retval, other_val, -1)}}
{% endset %}

retval should be 20: {{retval|trim}}
retval - other_val should be -4: {{retval2|trim}}
