Question

I am doing a divider circuit in verilog and using the non-restoring division algorithm.
I am having trouble representing the remainder as a fractional binary number.
For example if I do 0111/0011 (7/3) I get the quotient as 0010 and remainder as 0001 which is correct but I want to represent it as 0010.0101.
Can Someone help ??

Answer 1

Suppose, as in your example, you are dividing 4 bit numbers, but want an extra 4 bits of fractional precision in the result.

One approach is to simply multiply the numerator by 2^4 before doing the division.

i.e.

instead of 
0111/0011 = 0010 (+remainder)
do
01110000/0011 = 00100101 (+remainder)
