Re: PARI stable release 2.3.5 (for real now) |
Dear Ilya, Sorry, my mistake. Indeed, the exponential decrease would be [[1],3/2]. But a decrease in x^(-3/2) or x^(-2) is an ordinary slow decrease, so I maintain that one should use [[1],0], or equivalently simply [1]. I must admit that I do not remember what [[1],-3/2] would mean, but certainly not X^(-3/2), so on that point the doc is wrong. Perhaps "very slowly decreasing like X^(-z)" in the doc should be replaced by "very slowly decreasing like 1/(X\log(X)^z)", but I am not sure, need to be checked. Henri Cohen
