URL http://www.h108.com/stkman/soft/calcpro.zip 專業版1.0
作者：stkman[CCG] & arbiter[CCG]
簡述：BigInt Calculator 是一個支援超大整數運算的計算器,可以對長度最多達10000位10進位制的資料進行運算。
它不但支援普通的四則混合運算,而且具有位操作和表示式運算功能,計算器本身提供了21個存貯單元可供
儲存運算的中間結果,在表示式中可以引用這些儲存單元。
BigInt Calculator的一個顯著優點是軟體體積小，可執行檔案不足50K，純綠色軟體，不修改登錄檔。
upx加的殼，脫殼很簡單。
註冊檔案為calcpro.key，如內容不對會退出。
