Dave-
Thanks. I should have known better.
But I was misled by what I assumed was Perl's rules for how variables were used to build double-quoted strings. I would have thought that floating point numbers that are not integers would show enough decimal places to indicate such. That's how I was misled into thinking that these cases were identical. I realize that I actually don't know how numbers are evaluated for double-quoted strings. Do you have a good reference?
Regards,
John
