/*I am currently making a program you can draw lines in. If the distance between two points is bigger than 20 pixel, a line is drawn. The angle between the first and the second point is measured, and I want the colour of the line depending on the value of the angle. There´s no problem so far if the value of the angle isn´t a negative number, but as soon as it is, the line doesn´t get the colour I want it to. I suppose there´s something wrong with my writing of negative numbers, can somebody please tell me what it is? I just can´t find out!

Here´s the code area I´m talking about (I´m well aware that it unfortunately is not that nice and clean):*/
