It sounds like you're trying to compute the winding number of the field for a path around a point. Maybe http://en.wikipedia.org/wiki/Winding_number#Complex_analysis will get you started. If you want more advice about computing discretized line integrals, folks can probably provide suggestions about good ways to implement that.
