Function Documentation

KZ_INLINE void kzcSolveNormalizedQuadratic	(	kzFloat	P,
		kzFloat	Q,
		kzBool *	out_solutions,
		kzFloat *	out_solution1,
		kzFloat *	out_solution2
	)

Solves a quadratic of form x^2 + P x + Q = 0.

Avoids losing precision unnecessarily.

If there are no solutions, out_solutions will be KZ_FALSE. Otherwise, out_solution1 will be the smaller solution and out_solution2 will be the greater solution.
