Of course,

$number_of_numbers = length $test;

as well....

(which is a faster way...).

Not what I do is the
following

example!!

$number_of_numbers = "60";

$number_of_numbers = $number_of_numbers/40;

The result is 1.5

What I now need is that number will be roundoff up.

$number_of_numbers has to become 2.

But this roundoff has to be done not as we normal round off a number, but by the following way!!

0.5 becomes 1
0.2 becomes 1
1.2 becomes 2
4.7 becomes 5
3.02 becomes 4

How to do that!!

for example:
$number=56987658.09728794645;

$number=~m/(\d+)(\.)?(\d+)?/; $number=$1;
if ($2 && $3) {
   $number++ if $3>0;
}
print "$number\n";
