这是一个改进型计算器克服了浮点运算误差新增了报数和运算符改错功能，比起我上次做的代码质量更高，更简捷，算法也不一样。当前只支持基本的四则运算，非常适用！！！，美中不足是报音慢点，但对于手慢的使用者也足够了，对于大量快速计算建议关闭报数功能。在98上通过-This is an improved version of Calculator overcome the floating-point error in the newspapers a few new and Operators Corrector function, compared to the last time I do a higher quality of code, more simple, not the same algorithm. Currently only supports the four basic operations, very applicable! ! ! , Reportedly fly in the ointment is the sound slow, but for users of hand slow enough for a large number of fast computation reportedly recommended the closure of several functions. Adopted in 1998
