Calculation of interest of time deposit
定存利息的計算方式

For a CD at 1% interest,
many people think the the interest is 100000 X 0.01 = 1000 dollars.
It's wrong.
Actually, you'll get 1004 dollars.
You can get the number from 100000 X ( ( ( 1 + ( 0.01 / 12 ) ) ^ 12 ) - 1 ) = 1004.
以 100000 元定存一年利率 1% 為例,
很多人以為一年利息是 100000 X 0.01 = 1000 元, 錯!!
實際上你會拿到 1004 元的利息,
計算方式是 100000 X ( ( ( 1 + ( 0.01 / 12 ) ) ^ 12 ) - 1 ) = 1004 元
