Re: annoying symbols in logfiles

[Vasily Golyshev <golyshev@mccme.ru>]

Dear Karim,

thanks! I upgraded. By the way, what is the situation with the old bug
zetak() at high precision?
I think it still persists:

? \p300
   realprecision = 308 significant digits (300 digits displayed)
? fi=zetakinit(y^2+3);
? zetak(fi,3)
%56 = 2321810222847404308198257648797882740986532669962989186246788468182200204430510063851992267705037929938552253153797145598802881570332850226037739722285923862656462115230025507544290975.18809557156596075869632722124549255080717716389570001753456539965440047105141386127695979479427968042090138395816221
