Bug description:Unexpected result of int() conversion
Description:
------------
Putting an (int) in front of brackets creates a wrong result - or at least
an
unexpected result.
Output of below script is actually:
input = 0.58, output = 57
test3 = 58
test4 = 57
("0.58"*100) creates a correct 58
(int) ("0.58"*100) gives an incorrect 57
The same happens with input of "0.29", where the output = is 28.
It happens on intel as well as AMD cpus.
Test script:
---------------
$test = "0.58";
$test2 = (int) ($test*100);
$test3 = ($test*100);
$test4 = (int) ($test*100);
echo "input = $test, output = $test2\n";
echo "test3 = $test3\n";
echo "test4 = $test4\n";
Expected result:
----------------
I would expect the output to be:
input = 0.58, output = 57
test3 = 58
test4 = 58
Actual result:
--------------
Current output:
input = 0.58, output = 57
test3 = 58
test4 = 57
