多功能计算器，比window操作系统自带的计算器强大，功能介绍：

1.字符串数学表达式计算：3+9*8=75

2.多括号嵌套匹配计算：(3+9)*8=96

3.标准数学函数计算：sin(3)*mod(12,17)=1.69

4.逻辑表达式计算：2*2=4 and 27=3*9 = true

5.时间语句计算："时间："+string(today())

6.IF语句计算：if(2<4,1,0)=1-Multi-function calculator, window operating system than a powerful built-in calculator, function introduction: 1. String calculation of mathematical expressions: 3+ 9* 8 = 752. More nested parentheses matching calculation: (3+ 9)* 8 = 963. the standard calculation of mathematical functions: sin (3)* mod (12,17) = 1.694. logical expression the calculation: 2* 2 = 4 and 27 = 3* 9 = true 5. time calculation statement:　Time:+ string (today ()) 6.IF calculated statement: if (2 <4,1,0) = 1
