[计算器] BA II PLUS 计算器的问题

我的计算器型号是 BA II PLUS的
现在有一种情况就是,我计算PV、PMT、利率的时候,有时候算出来的结果跟教材不一样

我必须得按下 2ND RESET ENTER, 貌似是全部清空记忆,然后才可以算出正确的结果 这样子很麻烦

希望大侠们给我指教,如何避免这个问题

谢谢

It seems that everytime you should press 2ND RESET ENTER...

    Yes, that's what i am doing every time after each calculation, so i am wondering whether you have some quicker solution.
The problem is not this, the problem is I have to set 5 decimal places every time after re-set, which requires so much time
