How to round and keep floating digits

[juo]

Does anybody know how to perform roundings but at the same time convert integers to float using the rounding parameters. I have been using Math::Round for that purpose however it does not add zeroes. See example below.

#!/perl/bin -w

use strict;
use Math::Round; # Not standard with Perl delivered

my @number = qw(3 3.555 3.222334 3.4 1 0);

for my $float(@number) {
$float = nearest(.001, $float);
print "$float\n";
}

__END__

Result of Math::Round
3
3.555
3.222
3.4
1
0

This is what I want to get

3.000
3.555
3.222
3.400
1.000
0.000

You want printf or sprintf:

my @number = qw(3 3.555 3.222334 3.4 1 0);

for my $float(@number) {
    $float = nearest(.001, $float);
    printf "%.3f\n", $float;
}

Use printf "%5.3f\n", $float;

the following worked with perl, no need to use bash printf ("\n \t Pass Percentage = %0.2f %\n",$float); -Prasad
