dividing a number without using division operator in c [duplicate]

Answer 1

Psuedo code in python for divide by constant

n_bits = Number of bits of input over which division is expected to be accurate

den = divisor

prec = int(math.ceil(math.log(den,2)))
shift = n_bits + prec
mult = int(math.ceil((1<> shift
err = sum([round(x/den) - ((x*mult) >> shift) for x in range(1<

Multiplication can be implemented with shifts and adds
