Bug description: different behavior of rand, precission ini parameter has no
effect
Description:
------------
on php 5.2.1 the return value of the round function can be modified in its
precision via the "precision" ini parameter. but on php 5.2.3, the
precision parameter doesn't have any affect on the return value of the
round function. The phpinfo function displays the configured paramter,
therefore it can't be an configuration problem.
Reproduce code:
---------------
<?php
$number = 1200000;
$number = $number*1;
print "$number ".gettype($number)."<br>";
ini_set('precision','12');
print "precision: ".ini_get('precision');
$number = round($number);
print "<br>$number ".gettype($number);
ini_set('precision','6');
print "<br>precision: ".ini_get('precision');
$number = round($number);
print "<br>$number ".gettype($number);
$number = (int)$number;
print "<br>$number ".gettype($number);
?>
Expected result:
----------------
on php 5.2.1 you get:
1200000 integer
precision: 12
1200000 double
precision: 6
1.2E+06 double
1200000 integer
Actual result:
--------------
on php 5.2.3 you get:
1200000 integer
precision: 12
1.2E+6 double
precision: 6
1.2E+6 double
1200000 integer
