Read up on int division. Not my down-vote, but your Google skills need a little work. — Hovercraft Full Of Eels, Feb 23 '14 at 07:48

int/int = int

You have to make dx and len as double in order to get a double result else you can also type cast dx and len to double.

Try this:

xinc = (double)dx/len;

Also, before posting, Google.

int / int = int
int / double = double
double / int = double
