Bug description:round(1e15+0.1) returns 1e15+0.1 instead of 1e15
Description:
------------
When round() is called with 1 argument which value is between 1e15 and
2^53, round() returns non-rounded value even if the value has fractional
part.
For instance, though 1e15 is exact number as IEEE 754 double precision,
round(1e15+0.1) returns 1e15+0.1. I think 1e15 is better result.
Test script:
---------------
<?php
'ini_set("precision",18);
var_dump(round(1000000000000000.1));
Expected result:
----------------
float(1000000000000000)
Actual result:
--------------
float(1000000000000000.12)
