TYPO3 Core

If a page-type (pageNum) doesn't exist I get an Error, that's okay
E.g http://localhost/index.php?type=2

I get a page with:
Error!

The page is not configured! [type= 2][]
That's okay.

On the other hand, if I use a very long number in URL-paramter 'type' it returns a false Number in the error message, e.g.:

http://localhost/index.php?type=11111111111111111111
--> The page is not configured! [type= 9223372036854775807][]

or even
http://localhost/index.php?type=1111111111111111111111111
--> The page is not configured! [type= 9223372036854775807][]
(the same wrong number)

It seems to stand in context with data type 'int'
Number 9223372036854775807 is 2^63 - 1
