Three-in calculation functions:
1. Calc -- A calculator program not the same that provides 12 digits simple calculation.
Unlike most of the calculator program calculation rules, but the same with the most of the general commercial entity calculation which calculated each time the operator button clicked. That is not a calculator "multiply-divide first and then add and subtract", for the user needs such a computing.
2. Counter -- A Counter provide addition and subtraction calculations count. It can memory three digital sets and time passed.
3. Stop Watch -- Provide timing calculation, the minimum can count to the tenth of a second.

三合一計算功能 :
1. 計算機 : 提供12位簡單運算,計算規則不同於大多程式計算機,反而與大部份一般市售實體計算機同,即每按一次計算符號鍵就會執行一次運算,也就是不會[先乘除後加減],提供給有這樣計算需求的同好使用.
2. 計數器 : 提供加減計數計算,可記憶三組計數及其經過時間.
3. 碼表 : 提供計時計算,最小可計算到十分之一秒.
