Bug description: gmp_div_r does not preserve the sign of 1st argument
Description:
------------
PHP manual at http://ch2.php.net/manual/en/function.gmp-div-r.php
claims
for gmp_div_r:
-----
resource gmp_div_r ( resource $n , resource $d [, int $round ] )
Calculates remainder of the integer division of n by d . The remainder
has the sign of the n argument, if not zero.
-----
However,
print(gmp_strval(gmp_div_r(-5, 100)) . "\n");
Will result in "5", not "-5".
Reproduce code:
---------------
<?php
print(gmp_strval(gmp_div_r(-5, 100)) . "\n");
?>
Expected result:
----------------
-5
Actual result:
--------------
5
