A bank quote  certificate of deposit (CD) yields both as annual percentage
rates(APR),without compounding and as annual percentage yields(APY) that
include the effects of monthly compounding.A 100,000CDwillpay110,471.31
at the end of the year.Calculate the APR and APY the bank is quoting.
答案：
For APR,PV=100,000;FV=-110,471.31;PMT=0;N=12，CPT I/Y=0.8333， which is the
monthly rate. The ARP=12*0.8333,算出APR=10%
For APY,APY=(110,471.31/100,000)-1=10.471%

我的问题是：
APR是10%的话那一年后拿到的钱不应该是110000嘛怎么会110471呢？APR不是不带复利效果的嘛？
