back in during the next scan. In this manner, position information is not lost over
the course of the operation.
In the Absolute mode, the instruction can scale an input, such as position, without
losing any information from one scan to the next.
Calculating the Output and Remainder
The PMUL instruction uses these equations to calculate Out in either relative or
absolute mode:
Ans = ((DiffInput x Multiplier) + INT_Remainder)
INT_Out = Ans / 100,000
INT_Remainder= Ans - (INT_Out * 100,000)
Out = INT_Out
