Re: Ceiling elements of an array!

The POSIX module (part of the standard perl distribution) implements ceil(), floor(), and a number of other mathematical and trigonometric functions.

Example,

use POSIX;
$ceil = ceil(3.5);# 4

`use POSIX;` POSIX is big and pollutes your namespace with its very many function names. This may bite you when you make it a habit to use it just like that. Better import exactly what you need: it may pay off to `use POSIX qw(ceil floor); # import ceil() and floor()` Cheers, Sören Créateur des bugs mobiles - let loose once, run everywhere.

Hi Vinoth.ree, Thank for quick answer! But how can I apply that method for elements in array?	[reply]

how can I apply that method for elements in an array? Have a look at pme's answer... or go for loop constructs: foreach for small arrays or while for larger data. Cheers, Sören Créateur des bugs mobiles - let loose once, run everywhere. (hooked on the Perl Programming language)	[reply]
