Reading 2d array and editing

[abhik1368]

Well

I have a 2D array matrix file like

0.5 0.8 0.9 0.10 
1.0 0.5 0.75 0.6
2.5 6.0 0.5 0.53
3.0 2.75 0.9 0.5

I want to read this file as csv and edit the file such as when the values are above (> 1) i want to edit it as 1.0  
so my matrix will look like

0.5 0.8 0.9 0.10 
1.0 0.5 0.75 0.6
1.0 1.0 0.5 0.53
1.0 1.0 0.9 0.5

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

my @matrix;

while (<DATA>){
    chomp;
    push @matrix, [split];
}

foreach my $row (@matrix){
    foreach my $cell (@$row){
        $cell = no_more_than_1($cell);
    }
}

foreach (@matrix){
    print join ' ', @$_, "\n";
}

sub no_more_than_1{
    my $nbr = shift;
    if ($nbr > 1){
        return '1.0';
    }
    else{
        return $nbr;
    }
}
__DATA__
0.5 0.8 0.9 0.10 
1.0 0.5 0.75 0.6
2.5 6.0 0.5 0.53
3.0 2.75 0.9 0.5

I felt like it's fun and that I can improve on the previous solution.

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

while (<DATA>) {
print join "  ", map { $_ > 1.0 ? '1.0' : $_ } split / /, $_;
}

__DATA__
0.5 0.8 0.9 0.10
1.0 0.5 0.75 0.6
2.5 6.0 0.5 0.53
3.0 2.75 0.9 0.5

OUTPUT
0.5 0.8 0.9 0.10
1.0 0.5 0.75 0.6
1.0 1.0 0.5 0.53
1.0 1.0 0.9 0.5
