possible alternate code using printf() to round off the imprecision with a power of 10 in fractional base 2 math. 
#!usr/bin/perl
use strict;
use warnings;

my $j=0;
for (1..800) #loop 800 times
{
    $j+= 0.01;
    printf ("%0.2f\t", $j); #2 decimal places
}
__END__

Output:

0.01    0.02    0.03    0.04    0.05    0.06 ......
7.95    7.96    7.97    7.98    7.99    8.00
