Let's see, PPC:

	printf ("%.50f", atan2(1,1) * 4.0);

gives:

3.14159265358979311599796346854418516159057617187500 (same as Solaris above).
Accurate to here ^ as Brian McNett points out, which is where the NT 
truncates, so I wouldn't call it, er, precisely, a bug...

Meanwhile, Brian: great so far! Do you think Perl could ask out loud 
"accurate to how many digits?", then the user could just type in a 
number & hit return, and the script would speak it out? In due time 
of course, the user won't have to type it, but rather just tell the 
machine orally...
