It is not a windows bug, that's a sure thing.

That can't work, php does not support large integer. It may happen than
a 64 system (say compiled on a linux 64 or win64) gives this result, but
not a windows 32bits build.

There is already a request for large integer support > bogus.

I've tried 5.2.7-dev, but it gives me the same result.

And what does "nevermind" mean? It's a bug, and it have to be solved.
If we say nevermind to all of bugs we won't develop.

Mhh, maybe it's a windows bug, not a php bug?

thanks,

Nevermind, happens within all branches, but only with windows.

version was 5.2.1, not 5.2CVS-2008-08-18 (CVS)

Description:
------------
For too big numbers, intval returns a negative value

Reproduce code:
---------------
<?php
  $a = 25 * pow(1.5, 50);
  echo $a."<br>";
  echo intval($a)."<br>";

  echo "<br>";

  $a = 10 * pow(1.5, 60);
  echo $a."<br>";
  echo intval($a)."<br>";
?>

Expected result:
----------------
15940537505.4
15940537505

367684687169
367684687169

Actual result:
--------------
15940537505.4
-1239331679

367684687169
-1682500287
