Perl Question: Making a number string from left aligned to right aligned

I have a number string which is of length 10. The number is left aligned and I want to make it right aligned.
For e.g.
Input string = 12345.99  
Expected result =   12345.99

Input String = "120.87    "
Expected Result = "    120.87"

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this:
#!/usr/bin/perl
 
#Input string
$istring = "120.87    ";
#Expected Result
$ostring=sprintf("%10.2f",$istring);
 
print $istring;
print "\n";
print $ostring;
