Integer to String

[toofat]

Hi. I just need someone to tell me what am I missing ... please read comments inside code.

$IntegerA = 9876543210123456789
$StringA = String ($IntegerA)
; $StringA returns string 9223372036854775807 (expected string 9876543210123456789)


$IntegerB = 8876543210123456789
$StringB = String ($IntegerB)
; $StringB returns string 8876543210123456789 (returns as expected)

Thank you very much.
