We adapt the radix-r digit-recurrence division algorithm to complex division. By prescaling the operands, we make the selection of quotient digits simple. This leads to a simple hardware implementation, and allows correct rounding of complex quotient. To reduce large prescaling tables required for radices greater than 4, we adapt the bipartite-table method to multiple-operand functions.
