The previous post looked at an example of strange floating point behavior taking from book End of Error. This post looks at another example. This example, by Siegfried Rump, asks us to evaluate 333.75 y6 + x2 (11 x2 y2 – y6 – 121 y4 – 2) + 5.5 y8 + x/(2y) at x = … Continue reading Just evaluating a polynomial: how hard could it be?
