这是我的代码。我是c++语言的新手，我在课堂上被分配了一个项目，我必须计算房屋抵押贷款的月供。

我需要使用pow函数并将幂乘以一个表达式。下面是我的尝试:

(float)(MONTHLY_RATE*AMOUNT_MORG)*(pow(1.542,180))

，当我运行程序时，我得到的答案是1.#inf。

1.542180大于7,164,522,793,368,325,816,802,274,738,448,555。这是一个相当大的数字，你确定它适合你的浮点类型吗?

根据您下面的评论，看起来您想使用1.00542。

该信息的其他副本也是错误的(MONTHLY_RATE, FORMULA_RATE)。
