问题如下：
An investor invests $180,000 today . Assume the interest rate is 10% and the investment can coumpound daily. after 2 years, the value of the investment will be :
选项：
A.$217,800.
B.$198,928.
C.$219,846.
解释：
C is correct.
N = 2 × 365 ;
I/Y = 10 / 365 ;
PMT = 0;
PV = -180,000;
CPT FV = $219,846.47
先求出EAR=10.52%，然后根据N=2,I/Y=10.52,PV = -180,000;PMT=0,FV=219.864 与答案少许有出入
