I used BCD and CORDIC algorithms in the firmware I recently completed for the AriCalculator. I will rewrite the algorithms for multiplication and division using the multiplication and division assembly instructions (I used shift and add algorithms in the original firmware), but I think CORDIC algorithms are the best option for the transcendental functions for microcontrollers without a floating-point coprocessor.
