Those equation are different….
19% is equal = 19/100…

if the equation is work… it should be a simple truncation error in computer i.e. round of or dump value in bin.

i am using iMac G4 15′ 800 Mhz
When i try 100*1.1 and 100 10%, the answers are the same.
But when i try the above equations, different answers returned (even precision was set to 11) !!! so queer…….

My iBook rendered the same results in both methods.

將 precision set 做 11 或以下，無分別！

View Menu->Precision->11

Calculator的Behaviour和一般計數不同。

8511.22加19% 不等同於 8511.22加0.19，故此答案不是8511.41。當你在Calculator輸入8511.22加19%，即是做算術時的8511.22加8511.22 * 19%。

先不論CPU

這兩個算式根本上就寫錯了…

8511.22 * 1.19 不等於 8511.22加19%

應該改為

8511.22 * 1.19 = 8511.22 加 8511.22 * 19%
