The computation of the parameter s should be:

double s = segmentDirection.isVertical() ? (vector.y - segmentStart.y) / segmentDirection.y
					: (vector.x - segmentStart.x) / segmentDirection.x;

instead of:

double s = segmentDirection.isVertical() ? (vector.y - segmentDirection.y)
					/ segmentDirection.y
					: (vector.x - segmentStart.x) / segmentDirection.x;
