and 270 as -0.25 (or 3.pi/2). When these binary angles are added using normal [[twos complement]] mathematics the rotation of the angles is correct, even when crossing the sign boundary.

This technique was used in the 1970's and 80's for real time computing that was mathematically intensive, such as [[flight simulation]]. The code was often commented with the binary scalings of the
