Re^2: how to always round up in perl? (selective import)

in thread how to always round up in perl?

if you do not want to import a mass of functions into your namespace from the POSIX module

... just do this:

use warnings; 
use strict; 
use POSIX qw(ceil);

for (3.3, 3.6, 3003.3) {
    print $_, "\t", ceil($_), "\n";
}

__END__

3.3    4
3.6    4
3003.3    3004

According to How to Import, this selectively imports only the ceil function.

Alternately, you could import nothing and call the function using POSIX::ceil.
