lil_v has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I have a number in scientific notation and i want to transform it into a decimal number. I used sprintf for it but %f character length is limited to 6 digits after decimal. However if i specify the number of digits i need, the number is user generated so i would end up with trailing zeroes. Any suggestions? Here is my code: 
my $number = $base * (10**$power);
$p = sprintf("%u", $power);
$number = sprintf("%.20f", $number);

Instead of ".20", I would like to use the unsigned value of $power, I dont know how to go about it...

    What about... 
    my $number = $base * (10**$power);
$hto_visk0 = sprintf("%.${power}f", $hto_visk0);

        Can you give some examples of the output you expect to see from a range of different inputs?
