Hello cspctec,
You claim that the regex m/-\d+\d+\d+\d+\d+\d+\d+\d+\d+\d+\d+.*\..*/ “always matches” — but it doesn’t!
#! perl
use strict;
use warnings;
while (<DATA>)
{
chomp;
print "$_ is a match\n" if /-\d+\d+\d+\d+\d+\d+\d+\d+\d+\d+\d+.*\.
+.*/;
}
__DATA__
-523566.00
-0.0013
0.0045
-32742987982758110638106318307132432131.0000
Output:
21:30 >perl 543_SoPW.pl
-32742987982758110638106318307132432131.0000 is a match

Perhaps the problem lies in how you’re testing the regex against the data?
Incidentally, you can write an equivalent regex more compactly using the {n,} quantifier, which will “Match at least n times” (see “Quantifiers” in Regular Expressions):
/-\d{11,}.*\..*/
as per the answers above by moritz and BillKSmith.
Hope that helps,
