I am using this code:

$page = int(param('page'));

This sometimes results in:

warning: Use of uninitialized value in int

Is this a good solution to resolve this warning, or is better and more succinct code available?

if (defined param('page')) {
    $param_page = int(param('page'));
} else {
    $param_page = 1;
}

I was using this code to fetch a CGI parameter:

$page = int(param('page'));

This sometimes results in:

warning: Use of uninitialized value in int

Is this a good solution to resolve this warning, or is better and more succinct code available?

if (defined param('page')) {
    $param_page = int(param('page'));
} else {
    $param_page = 1;
}
