e/Dual quaternion

Information
has gloss	eng: In ring theory, dual quaternions are a noncommutative ring and a nonassociative ring constructed in the same way as the quaternions, except using dual numbers instead of real numbers as coefficients. A dual quaternion can be represented in the form q = q0 + ε qε, where q0 and qε are ordinary quaternions and ε is the dual unit (εε = 0).
