What have you tried? Why has it not worked? See How (Not) To Ask A Question. As this is connected to previous threads (I assume a use for hashes?), you should reference them so other monks can follow and assist. You also should not put an entire post in <code> tags - it makes exposition more difficult to read. See Writeup Formatting Tips.

I do not entirely follow how your input maps to your output, even after reading the previous thread. Based upon my best guess, you should use a hash of arrays of arrays - see perllol for info on more advanced data structures. Note that while Perl would handle the scientific notation value with no difficulty, it doesn't matter since you are not doing math with it. As far as Perl is concerned, this is just a series of space-delimited strings. Does this do what you intend? 

#!/usr/bin/perl
use strict;
use warnings;

my %relays;
while (<DATA>) {
    chomp;
    my @result = split /\s/;
    my $id = shift @result;
    for my $i (0 .. $#result) {
        push @{$relays{$id}[$i]}, $result[$i];
    }
}

for my $id (keys %relays) {
    for my $field_ref ($relays{$id}) {
        for my $values_ref (@$field_ref) {
            print "$id @$values_ref\n";
        }
    }
}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
