一,实现功能

1、二进制、八进制、十进制及十六进制数的加、减、乘、除、乘方、取模等简单计算

2、科学计算函数，包括(反)正弦、(反)余弦、(反)正切、(反)余切、开方、指数等函数运行

3、以角度、弧度两种方式实现上述部分函数

4、具备历史计算的记忆功能

-First, the realization of the functional 1, binary, octal, decimal and hexadecimal number of add, subtract, multiply, divide, involution, such as simple calculation modulus 2, scientific computing function, including the (Anti-) sinusoidal, (anti-) cosine , (anti-) tangent, (anti-) Cotangent, prescribing, the index function, such as running 3 to the angle of curvature of two ways to achieve the above-mentioned part of function 4, with the history of computing and memory function
