If $power is negative, you should define another var equal to -$power.

      Well, this works for me.

      use strict;
use warnings;

my $base=2;
my $power=-12;
my $number = $base * (10**$power);
my $p = abs($power);
my $string=sprintf("%.${p}f", $number);
print $string;

        You can also supply the field width as one of the args that you put after the format string, by putting "*" in the format where that numeric should go: 
        my $string = sprintf( "%.*f", $p, $number );
