Programming and I

I don't want you to think I think that I'm a professional programmer. Programming is not my specialization. However I am able to do something (to see my AVR Assembler skills check out my individual work)

Turbo Pascal was the very first language I used. Truthfully I used it very very long ago. After Turbo Pascal I learnt C++ for some time. But my „native“ programming language is Delphi. I used it for some course projects in university and also I coded for myself, it was my hobby. Most difficult was a program for solving algebraic equations. For example I will show how this program solves the equation f(z) = 0, where

f(z) = z⁴ + (z + 3)³ − 7·z³

On the next image you may see the program with appropriate input for solving this.

If we use Mathcad for checking the result (z = 6.686111) we will find out that our function f(z) does not actually return zero (the picture below). It returns 0.00044. Not very good result but accuracy may be increased if it's necessary
