Toying with the Borel summation to calculate tetration
#11
@mike3

Code:
...
pdegree = 108;
\ps 119;
...
/* Real tetration */
p = 1
p = nnormiters(25, p, 28, 2)
...
I run *.gp, this file is loading during 13 seconds* and digit "realtet(0.5)". finally I got 1.646354241102910308272044832. I will get better result... Wink

* - running my CPU Core 2 Duo E6600 OC to 3.0GHz. Smile what is your CPU? how much time are you loading (same "\ps", n=25, ubound= or A=28...)

The settings were mentioned in my post (by the way, ps and pdegree should be equal, or ps greater than pdegree by 1, ps is the "series precision" in number of terms, pdegree the degree of the highest term.).

CPU is Core 2 Quad Q6600 at stock.
