How do you like my RNG?

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

use Time::HiRes qw ( usleep );
$| = 1;

print "number of digits: ";
my $num = <STDIN>;
chomp $num;


if($num < 1){
    print "grirrrrr. You can't do that! Number must be 1 or greater!!!
+\n";
    exit(0);
}



print randmiz0r($num);





sub randmiz0r{

    my $digCount = shift;
    my $digCountChanging = $digCount + 1; #offset for first subtractio
+n
    my $results = "";
    
    for(my $i = 0;$i < $digCount;$i++){
        
        my $randInput   = 1 . (0 x ($digCountChanging - 1));
        
        #retreave the last diggit
        my @prepLastDig = split //, &randmore($randInput);
        my $lastDig     = pop @prepLastDig;
        $results        = $lastDig . $results;
        
        #sleep because rand funct is time based
        usleep( int rand int rand 10000 ); # sleep for microseconds
    }
    
    if($results =~ m/^0/){
        $results = catchStartZero($results); #numbers like 0345 don't 
+exist
    }
    
    return $results . "\n";

}


sub randmore{

    my $r = shift;
    my $oddCatch = $r % 2;
    $r = $r - $oddCatch;

    return (int (rand $r) + int (rand $r));

}


sub catchStartZero{

    my $removeZero = shift;
    $removeZero =~ s/^0//;
    
    my $notZero = 0; #confusing but nessisary
    
    until($notZero ne "0"){

        chomp $notZero; #a \n is returned with randmiz0r()
