[Bug] SowyaApp 在 clox 模式下, 设置计算模式后自动退出clox模式.
:mode clox
setmode(1); //执行完此语句后自动退出 clox 模式
Version: 0.579

目前版本 v0.576, 计算 $(-\frac{1}{3})^{-\frac{3}{2}}$,
>> (-1/3)^(-3/2)
in> (-1/3)^(-3/2)
out> 0.00000000-0.19245009i
------------------------
正确答案应该是 $-5.19615242i$.
\[
(-\frac{1}{3})^{-\frac{3}{2}}=\frac{1}{(-\frac{1}{3})^{\frac{3}{2}}}=
\]

已修复部分. Calculator.cpp 中调用 A.ChangeInfix_InModeFraction();
temp = A.ChangeInfix_InModeFraction();
//temp = A.ChangeSymbolicInfix_InModeFraction();//仍有BUG
//temp = A.ChangeSymbolicInfix();
但还是有问题

Switch into fraction calculating mode.
e.g., 1/2+1/3 will return 5/6

不过没有化简.

求解一元三次方程 solve(x^3+x^2-3x+6==0)
对于 Sowya.exe version>0.551 且<=v0.554 的版本
>> solve(x^3+x^2-3x+6==0)
直接退出
目前在 v0.555 版本中已经修复.
