Function Documentation

coefficient crossing	(	const Line &	line1,
		const Line &	line2
	)		[inline]

Finds crossing point of two lines. Returns NAN if the lines are parallel.

std::ostream& operator<<	(	std::ostream &	output,
		const Line &	line
	)		[inline]

Prints line in format line.slope()*x + line.intercept()

int parallel	(	const Line &	line1,
		const Line &	line2
	)		[inline]

Tests if line1 and line2 are parallel. Fudges it a little bit to help with numerics.
