Random Selection

[BenRussell]

Say i have an array that looks like
@Values = ("1", "2", "3", "4"

How do I select a random one of these and assign it to
"$SelectedValue"?

This will not necessarily be the numbers as in the actual script they will change depending on certain other things, so how would I do this?

Thank you.

use POSIX;

$SelectedValue = $Values[floor rand @Values]; Brad Gunsalus

I would use the following:


@Values = qw(1 2 3 4);

$rand_value = $values[rand @Values];

print $rand_value;

Basically same as bardley

 

[bardley]

Yup. Use his.

Only wrote mine using floor() because I wasn't sure what perl would make of something like myarray[3.86572300276...] instead of myarray[3], but I should've known Perl would know what to do!
