Django / Python 计算
我正在构建一个小项目，允许用户获得项目资金。
一个项目有一个名为“amount_raised”的字段，它可能包含一个整数，例如“123.34”，
当通过 paypal 成功付款时，您会收到 ipn_obj，其中包含一些财务信息，即 ipn_obj.mc_gross 可能是“10.23”，
我如何在 django 中执行计算以获得其总值？
这是我第一次在 django 中处理计算，所以请耐心等待。
如果我尝试将它们转换为整数，我会收到错误 invalidliteral for int() with base 10
非常感谢您的帮助。
I am building a small project that allows a user to get funding for a project.
A project has a field called "amount_raised" that might house an integer such as "123.34"
when a successful payment is done through paypal you receive the ipn_obj of which one contains some financial info, i.e. ipn_obj.mc_gross which might be "10.23"
how do I perform a calculation in django to get the total value of that?
It's the first time I have dealt with calculations in django so bear with me.
If I try converting them to integers I get an error invalid literal for int() with base 10
Your help is much appreciated.

像 123.45 这样的数字不是整数。您需要的是 DecimalField。用法示例：
