在django模板中将float转换为int并将其相乘

# custom_filters.py
from django import template

register = template.Library()

@register.filter
def float_to_int(value):
    return int(value)

@register.filter
def multiply(value, arg):
    return value * arg

{% load custom_filters %}

{% with float_value=3.14 %}
    {% with int_value=float_value|float_to_int %}
        <p>转换后的整数值：{{ int_value }}</p>
        {% with result=int_value|multiply:2 %}
            <p>相乘后的结果：{{ result }}</p>
        {% endwith %}
    {% endwith %}
{% endwith %}
