<?php
// PHP Version 5.2.9
$arr = array(75.6, 75.6, -226.8, 75.6);
var_dump(array_sum($arr)); // float(-2.84217094304E-14)
?>
Result is not 0. Why?
Thank you.
This not the problem of
array_sum,echo 75.6+75.6-226.8+75.6;also give you the same result. This is the problem that how computer treats the float number. See here(Floating point) for more information.
