WebAfter a quick inspection, it seems that the buffered samples, in the $1+z^{-1}$ cells of increasing index, have an increasing order of magnitude. It helps when I use long double , but this becomes insufficient when the order is of the order of 60: we loose a lot of numerical precision when we combine floating-point values of around $10^{10 ...
