此算术表达式能够在程序运行时根据输入的变量大小和算术表达式动态解析表达式，得到运算结果。支持多项算术运算符和数学函数如下：: + - * / ^ ( ) mod abs, atan, cos, exp, ln, round, sin, sqrt, sqr, trunc 例如设定a1和a2的大小，就可计算下列表达式: exp(sin(a1)*cos(a2))操作系统： Visual C++语言 -this arithmetic expression in accordance with the procedures in the importation of variable size and arithmetic expressions dynamic analytical expression to be Operational results. Support for a number of arithmetic operations and mathematical functions are as follows : :-*/^ () mod abs, atan, cos, exp, ln, round, sin, sqrt, sqr, for example, to set trunc a1 and a2 the size, can be calculated by the following formula : exp ( sin (a1)* cos (a2)) Operating System : Visual C language
