代码说明：

能运算的函数： sin,cos,tg,ctg,e^,pow(x,y),cosh,sinh,tgh,log10,ln,sqrt,arcsin,arccos, 运算方式： +,-,*,/,绝对值（“[ ]”）,^,!, 输入规则： 用键盘或按钮都可，输入完按回车运算，(光标要在最后) sin(21-32)/(12-43) 4(323-4343) 4*(323-4343) e^2-sin3-3^4,(不要输入pow(3,4)) //有无*都可 2*3^4是（2*3）^4 而不是2*(3^4) 也就是要用x^y就要一定要（x^y）加上一个括号 [3-4]是求3-4的绝对值不是中括号 -performance computing functions : sin, cos, tg, rays, e ^, pow (x, y), cosh, sinh, tgh, log10, ln, sqrt, Simulation, arccos computational methods : absolute ,-,*,/, ( "[]"),^,!, importation rules : a keyboard or buttons which can be imported by the transport operator End (cursor to the final) sin (21-32)/(12-43) 4 (323-4343) 4* ( 323-4343), e ^ 2- KF-3 ^ 4 (do not enter pow (3,4))//* there can be 2* 3 ^ 4 is (2* 3) ^ 4 rather than 2* (3 ^ 4) was needed x ^ y must have (x ^ y) with a brackets [3-4] is the pursuit of 3-4 is not the absolute value of the brackets
