approxEqual bool approxEqual(Quaternion!(T) a, Quaternion!(T) b, T eps): Returns true if the distance between the given two point is less than eps.
length T length(Quaternion!T q): Returns length of a quaternion.
lengthSq T lengthSq(Quaternion!T q): Returns length of a quaternion.
normalize Quaternion!T normalize(Quaternion!T q): Returns a quaternion whose length 1 from target quaternion.
rotate Vector!(T, 3) rotate(Quaternion!(T) q, Vector!(T, 3) vec): Rotate a vector by a quaternion.
safeNormalize Quaternion!(T) safeNormalize(Quaternion!(T) q): Returns a quaternion whose length 1 from target vector. When the length is 0, returns zero quaternion.
slerp Quaternion!(T) slerp(Quaternion!(T) q1, Quaternion!(T) q2, T t): Interpolate two quaternions spherically.
toMatrix3 Matrix!(T, 3, 3) toMatrix3(Quaternion!T q): Converts a quaternion into matrix 3x3.
toMatrix4 Matrix!(T, 4, 4) toMatrix4(Quaternion!T q): Converts a quaternion into matrix 4x4.
