How can i get the degree direction from x1 y1 to x2 y2?example…  
x1 = 0 y1 = 0  
x2 = 100 y2 = 100  
Its equals 45°…  
I tried to make it myself but it not 100% accurate method…its showing 10-15 more degrees than needed…

Example:

```auto
float x1, y1, x2, y2;

void setup(){
  size(800,800);
  x1 = 400;
  y1 = 400;

}

void draw(){
  x2 = mouseX;
  y2 = mouseY;
  background(0);
  stroke(255);
  line(x1,y1,x2,y2);
  line(x1, y1, x1+100, y1);
  noFill();
  float a = atan2(y2-y1,x2-x1);
  arc(x1,y1,80,80, min(0,a), max(0,a) );
  text( degrees(a), mouseX, mouseY-20 );
}
  
void mousePressed(){
  x1 = mouseX;
  y1 = mouseY;
}

```
