2.2 Floored Division or Modulo Division

Floored division is defined as follows

Quotient = floor(Numerator/Denominator)
Remainder = Numerator – Quotient*Denominator

The function is defined such that the remainder will always have the sign of denominator. The function is linear around the zero point. The transfer function of the floored division is provided in Figure 2. This division function is more regular compared to the traditional division function.
