( #3333=superdoc: print w/ replies, xml ) Need Help??
I have a device that I'm connecting to via a perl script and outputting the numerical values it sends the script. The problem is, sometimes the device screws up and sends extremely large negative numbers to me, which it is not suppose to do.

The normal output from the device is:

-523566.00 -0.0013 0.0045

It could output numbers like the above (which are good outputs). However, sometimes it outputs garbage like this:

-32742987982758110638106318307132432131.0000

I'm trying to create a regular expression that will match large negative numbers and not the smaller ones. If I do something like:

my $match =~ m/-\d+\d+\d+\d+\d+\d+\d+\d+\d+\d+\d+.*\..*/;

It always matches. Can someone help me make a regular expression that matches only large negative numbers?
