问题如下：
A bank quotes a stated annual interest rate of 4.00%. If that rate is equal to an effective annual rate of 4.08%, then the bank is compounding interest:
选项：
A.daily.
B.quarterly.
C.semiannually.
解释：
A is correct.
The effective annual rate (EAR) when compounded daily is 4.08%. EAR = (1 + Periodic interest rate)m – 1 EAR = (1 + 0.04/365)365 – 1 EAR = (1.0408) – 1 = 0.04081 ≈ 4.08%.
看答案EAR计算只带入0.04，应该是0.0408，如果全部答案精确输入数据，有差异性，默认选差异最近的还是一定选个比提干要求高的值
