Description:
------------
PHP 5.03 appears to handle math equations with negative exponents
differently than PHP 4.3.x. I am trying to use the following example
in a larger script, but the primary difference is included below.
Reproduce code:
---------------
PHP 4.3:
<? echo (-4738698913^43814); ?>
outputs:
-443704711
PHP 5.03:
<? echo (-4738698913^43814); ?>
outputs:
-2147439834
Expected result:
----------------
I believe 5.03 should output what 4.3 does, but this is an
extraordinarily large number so I can't say for certain.
PHP 4.3:
<? echo (-4738698913^43814); ?>
outputs:
-443704711
Actual result:
--------------
PHP 5.03:
<? echo (-4738698913^43814); ?>
outputs:
-2147439834
------------------------------------------------------------------------
