hello, i find something strange, but as i don't know how to handle it, i ask here .... hoping for some answer

i have this code (simplified) i tested it under Perl v5.10.1 and v5.14.2 

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

my $i;
my @array;
for $i ( 0..150 ) {
    $array[$i][0] = $i;
    $array[$i][1] = $array[$i-1][1] + 0.2;
    print "$array[$i][0]\t$array[$i][1]\n";
}

exit;

which give me this output : 

.... some lines
148    29.7999999999999
149    29.9999999999999
150    30.1999999999999

a strange thing is, if you make a loop for ( 0..100 ) there is no problems

have you seen this kind of thing ? is it a (known ?) bug ? or something else that i can fix in my code ?
