Hey guys, I need help with something related with TI BASIC.
I made a quadratic equation solver, and made it so it could display non real answers, the problem is, when the root of a number isn't exact it will display it as decimal. Is there any way to make the program so it displays the answers as simplified roots?

Here's my program
+ Show Spoiler +

Take this quadratic equation as an example:
4x²+4x+4=0

For example, I would like the answers of this equation to be displayed as this:
(-1+i√3)/2
(-1-i√3)/2

instead i get
-1/2+.866025403...
-1/2-.866025403...

(the ... actually appear in the calculator)
All help appreciated... thanks!

What's the difference between Upper confidence tree and Monte-carlo tree search? Other than the UCB1-selection algorithm. Why do they refer to it as the "upper confidence tree", and not just "MCTS with another in-tree selection method"?

It makes no sense. Please help =).

Best way? --> get a Computer Science degree, pref. in sweden, we got really really good CS programs.

Hobby? google for some programming introduction/tutorials.

It's a question that has been posted a million times - check through this topic, you'll find an answer here.

Assuming you go the hobby route (which is a good way to evaluate if you really want to fly to sweden for a 3 year degree) - i would suggest googling 'Python tutorial' or similar.

Python is a great beginners language because its syntax is almost plain english and its very quick to setup and bang out an example program.

It's 4am here and I have until 1pm to finish my task.
We have to make a game in C++ following a requirement table, and I got stuck with Method Overloading and Operator Overloading (2 operators overloaded required). <_<
I have no idea what/how to do Operator Overloading and Visual doesn't run the game with Method Overflow (Stack overflow fatal error).
Can anyone help me? D:

void do_move(Move m) { ... } //do a single move
void do_move(Move m_array[], int n) { ... } //do n moves in m_array

class Board {
private:
   Square squares[8][8];
//...
public: 
   Square operator()(int i, int y) { return squares[i][j]; }
//...
}

//yo you can access the board like
Board game_board;

Square s = game_board(3,3);

edit:

I cant afford college or other courses
I started learning from w3schools.com, but its sooo much

any pointers, what should be the logical path to be a webprogrammer in 1-2 years?

Stack overflow usually means you have non terminating recursion.

Maybe there is some sort of hidden recursion. Like you are creating an object of type B in the constructor of A and vice versa. But without actually seeing at least the code that produces the problem it's hard to tell.
