Bug description:Incorrect conversion between float and int
Description:
------------
If I multiply 19.99 with 100 and cast it to int, I expect a value of 1999,
but I
get 1998. I verified this on 5 different php 5.4 installations on Mac OSX
10.8.2,
Debian and Ubuntu.
Test script:
---------------
<?php
var_dump('TEST #1');
var_dump($x = floatval(19.99 * 100));
var_dump($x = intval($x));
var_dump('TEST #2');
var_dump($x = floatval(1999));
var_dump($x = intval($x));
Expected result:
----------------
string(7) "TEST #1"
double(1999)
int(1999)
Actual result:
--------------
string(7) "TEST #2"
double(1999)
int(1998)
