Looks like Jerry doesn't know what an integer is either.
A hex number of course *is* an integer, unless its a hex representation
of floating point.
Killfile the prat like I have.

Don't expect Jerry to have a clue
because its either an integer number or a non numeric string?
I have given up trying to second guess PHP in casting.
One keeps things very simple as with a 2 year old (or jerry) when using PHP.
It can understand 18
It can understand 'eighteeen'
Lord knows what it does with '18'
As for 0x12...man, you are pushing the boat out, there.
Stop expecting PHP to be more than it is, a quick hack that writes good
web pages faster than almost anything else.
If you want a language that has a rule set and sticks to it rigidly,
that's C.
