Bug description:Casting from string containing exponential notation number to
int
Description:
------------
When trying to cast a numeric string value in the exponential notation to
int, the
result doesn't match with the initial value. While the casting to float
from
string works well. Also casting to int from the same value stored in a
float
variable workes well.
The function intval() has the same problem.
Test script:
---------------
<?php
echo 1E2 . "<br />";
echo (float)1E2 . "<br />";
echo (int)1E2 . "<br />";
echo intval(1E2) . "<br />";
echo (float)"1E2" . "<br />";
echo (int)"1E2" . "<br />";//problem
echo intval("1E2") . "<br />";//problem
?>
Expected result:
----------------
100
100
100
100
100
100
100
Actual result:
--------------
100
100
100
