The Logarithmic Number System (LNS) offers much better performance (in terms of Power, speed and area) than floating point for multiplication, division, powers and roots. Moderate-precision addition (of like signs) in LNS generally can be done with table lookup followed by interpolation, whose implementation can be as, or more, efficient than the equivalent precision floating-point adder. The problem with LNS is the size of the table needed for subtratction.
