See perldoc -q 'round'. Given that you want to round a floating point value
in a specific direction (up) and then pad the number out a certain number of
zeroes, I don't know of a simple solution. You will likely need to write
your own function, perhaps some combination of splitting on the decimal and
using POSIX::ceil.
Unless, of course, you didn't actually mean you want to round up, just that
you want to round, in which case you should take Bob Showalter's advice and
use sprintf or printf.
