Unexpected error message "Price must be positive number." when editing an item with price greater than 2147.00

[nikk0s]

Osclass 5.1.2
Unable to edit an item when price greater than 2147.00 ("Price must be positive number." error)

In some platforms (32 bits), also where PHP_INT_MAX=2147483647,
the sign test (int)$aItem['price'] < 0 may produce unexpected result if item price greater than 2147.00
and also ItemActions->validateCommonInput() method will failed
(since price is multiplied by 1,000,000 before validation and store in database)

To Reproduce
Steps to reproduce the behavior:

1. Edit an item
2. Set a price greater than 2147.00
3. Save
   -> save failed with error: "Price must be positive number."

Expected behavior
Save successfull

Bug Fix
Replace line 456 in ItemActions.php:
$flash_error .= (($aItem['price'] !== null && (int)$aItem['price'] < 0)
by:
$flash_error .= (($aItem['price'] !== null && (float)$aItem['price'] < 0)
