Demonstrates how to handle large integers in JSON. (Integers larger than what can fit in a 32-bit signed integer.) AutoIt

Local $bSuccess = False

; Let's say your JSON has this:

; {
; 	"id": 20000000001234567
; }

$oJson = ObjCreate("Chilkat.JsonObject")

$bSuccess = $oJson.LoadFile("qa_data/json/large_int.json")
If ($bSuccess = False) Then
    ConsoleWrite($oJson.LastErrorText & @CRLF)
    Exit
EndIf

; The integer is too large for a 32-bit signed integer that is returned by IntOf.
; The result will be something that wrapped around and could be negative.
; In this case it would be: -543893881
Local $id = $oJson.IntOf("id")
ConsoleWrite("id: " & $id & @CRLF)

; The solution is to read the integer value as a string, and then use the features in your programming language
; to convert from a string to a 64-bit integer.
; 
; Alternatively, you may wish to simply hold the value as a string.  If, for example, the integer simply references
; an order ID, an account ID, etc., then there's no need to convert to an integer value.  You're not going to be doing
; mathematical operations on it anyway.  This is usually the case for large integers -- they typically exist
; in JSON as an account ID.

; You can get any JSON value as a string:
Local $sAccountId = $oJson.StringOf("id")
ConsoleWrite("accountId: " & $sAccountId & @CRLF)

; Sample output:

; id: -543893881
; accountId: 20000000001234567
