If YOU create a child process then YOU should store the PID that the

Hi all,
I have a CGI script which does a select on a database and builds a checkbox

passed.

Take a look at Math::BigFloat, it's an arbitrary length float math package:

Hi Peter,
This is a floating point issue. It is a general computing problem and not
just subject to Perl. In decimal form the result
is -0.0017763568.
Generally thats usually acurate enough. Otherwise you could truncate it or
round it to the nearest quadrabillionth.

Hi Bob,
I'm doing data-processing (EDI). I need to format and present values in
text, round here and there. Have lots of various attempts that have failed
for one math related reason or another. Currently I convert to a string
and split and round, etc. (Even modulo '%' has failed me at times).

You might add a couple to the size of the length, but otherwise I would do all
my checking
That is what I am currently doing.
So $maxwidth= length $mylargeststring
But if I then set the width to that length it does not work. Its still
to short.
Any ideas?

I tried @PSARRAY = `command | grep bf1`; and got just the lines with

I need to delete oldest modified file in a directory. I find this file with this:
my $oldest= printf "%s\n", (sort{ (-M $b) <=> (-M$a) } glob("v:\*"));
print $oldest;
unlink "$oldest";
What I get in response is:

File is not deleted.
How would I do it?

Without more specifics I can show you how to get the data. This is
assuming a lot because I am confused about what you want to do.
