请问I/Y = 10%/12 计算器是怎么计算？是等于0.83还是0.0083？所有数字都带进去算了，就是这里算不对，结果无论如何答案都算不出来。

I/Y不带百分号，等于0.83

我的输入N = 300; I/Y = 0.83; PV = -1,875,000 ; FV = 0; CPT PMT = $16985.29。。。助教~这是我的计算过程，但答案还是算不出$17038。。也不知道问题出在哪里。。。

我算了一下，I/Y不能直接用两位小数计算，应该是10/12=0.833333333.....后面的位数不能省略。可以先按10/12=083333333...后，直接按I/Y，就能得出答案的结果。别的输入都没有问题
