Kahan summation algorithm: Support by libraries, Possible invalidation by compiler optimization & Accuracy

In numerical analysis, the Kahan summation algorithm, also known as compensated summation, significantly reduces the numerical error in the total obtained by adding a sequence of finite-precision floating-point numbers, compared to the naive approach (a summation algorithm). This is done by keeping a separate running compensation (a variable to…
