New Comment:
There's is just "number" type in JSON for numbers. And as such, this is
working just like it should and PHP tries it's best at guessing what
type the numbers might be.

Description:
------------
json_encode()-ing an integer when it is represented as floating point
number results in a change of type when json_decode() decodes the
output.
Examples of such floating point numbers are: -123.0, -1.0, 0.0, 1.0,
123.0
Reproduce code:
---------------
<?php
function jsonRoundTrip($f) {
$e = json_encode($f);
$d = json_decode($e);
var_dump($f, $e, $d);
echo "\n";
}
jsonRoundTrip(12.3); // This is a float
jsonRoundTrip(12); // This is an integer
jsonRoundTrip(12.0); // This is an integer represented as a float
jsonRoundTrip(0.0); // This is an integer represented as a float
?>
Expected result:
----------------
float(12.3)
string(4) "12.3"
float(12.3)
int(12)
string(2) "12"
int(12)
float(12)
string(4) "12.0"
float(12)
float(0)
string(3) "0.0"
float(0)
Actual result:
--------------
float(12.3)
string(4) "12.3"
float(12.3)
int(12)
string(2) "12"
int(12)
float(12)
string(2) "12"
int(12)
float(0)
string(1) "0"
int(0)
