Wow, nice variety of different results.... My version was: `This is perl 5, version 16, subversion 3 (v5.16.3) built for MSWin32-x +86-multi-thread (with 1 registered patch, see perl -V for more detail) Copyright 1987-2012, Larry Wall Binary build 1604 [298023] provided by ActiveState http://www.ActiveSt +ate.com Built Apr 14 2014 14:32:20` [download] on `Vista Home Premium, Service Pack 2, 32 bit architecture.` [download] It seems to indicate there is some kind of glitch with my implementation. Maybe it's time to upgrade. Thanks for your inputs.	[reply] [d/l] [select]

Wow, nice variety of different results Note that -1.#IND, nan, -nan and NaN are just different ways of denoting the same value - namely "not a number". Cheers, Rob	[reply]
