The converter can therefore also be used to normalize a rotation matrix or a quaternion. All input is normalized to unit quaternions and may therefore mapped to different ranges. For more information on the quaternion forms, see Algorithms. The idea for quaternions occurred to him while he was walking along the Royal Canal on his way to a meeting of the Irish Academy, and Hamilton was so pleased with his discovery that he scratched the fundamental formula of quaternion algebra, i^2=j^2=k^2=ijk=-1, (1) into the stone of the Online calculator for multiplying a quaternion by a real value This function multiplies the individual fields of a quaternion by a real value.
