Description:
------------
This bug is for the function intVal( ), and I also found that
typecasting with (int) produces the same results.
This is a very weird bug I encountered because of a price that is 19.99
and our processor requires it to be sent as 1999. 1999 is the only
value I was able to find that doesn't work correctly, but I'm sure
there are others.
I also checked it on a linux system with an older version of php 4 and
got the same results. I upgraded our php to 5.1.2 then tried it again
after it failed. I suspect the bug to be a floating point issue, but
I'm not certain of it.

Reproduce code:
---------------
<?php
$test1 = intVal(1999);
$amount = 19.99 * 100;
$test2 = intVal($amount);//value is 1998
$test3 = intVal("$amount");//value is 1999
echo $test1 . "<br />\n";
echo $test2 . "<br />\n";
echo $test3 . "<br />\n";
?>
Expected result:
----------------
1999
1999
1999
Actual result:
--------------
1999
1998
1999
