For instance, I can control the length for a string in the example below and get a print as "Vina" 
my $string = "Vinay";
printf('%-4.4s', $string);
print "\n";

The below set of statements prints 40000. How can I control the length of the float using printf to print 4000 even though the value of num is 40000? 
my $num = 40000;
printf('%4.0f', $num);
print "\n";
