You had perhaps already tried, but the Plouffe's inverter http://pi.lacim.uqam.ca/eng/ can't identify your number.

If you have a number-identifying program, and the time, can someone please tell me if this number, to 20 places, seems to be expressible in closed form* ? 0.33650841691839529162 (I have no strong reason to believe it can be, or can't be.) Many thanks -- and I greatly appreciate all the advice I got for numerically solving two eqns., two unknowns. --Dan _______________________ * You know what I mean. _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
