WebIn numerical analysis, the Kahan summation algorithm, also known as compensated summation,[1]significantly reduces the numerical errorin the total obtained by adding a sequenceof finite-precisionfloating-point numbers, compared to the obvious approach. WebThe floating-point emulation scheme discussed here is the block floating-point algorithm. The primary benefit of the block floating-point algorithm emanates from the fact that operations are carried out on a block basis using a common exponent. Here, each value in the block can be expressed in two components − a mantissa and a common exponent.
