Given that the input is a sequence of random numbers, you could synthesize your desired arrangement of bins directly with no loss of information:

use feature ":5.14";
use warnings FATAL => qw(all);
use strict;
use Data::Dump qw(dump pp);

sub bins($$$$)# Fill some bins
 {my ($start, $count, $width, $samples) = @_; # Start bin, number of b
+ins, bin width, number of samples
  my $bins;
  $bins->{$start+$width * int(rand $count)}++ for 1..$samples;
  $bins
 }

pp(bins(-2, 3, 2, 8));

Produces:

{ "-2" => 4, "0" => 1, "2" => 3 }
