#41045 [NEW]: intval returns different values, depending on the PHP version

From: xris01 at free dot fr Operating system: Debian Sarge PHP version: 5.2.1 PHP Bug Type: Math related Bug description: intval returns different values, depending on the PHP version Description: ------------ I understand that floats are expected to overflow when converted to int. What I don't, is why I don't have the same result on the same hardware with 2 versions of PHP : Reproduce code: --------------- $var = -2302452860; echo 'var_dump($var) = '; echo var_dump($var); echo "<br>"; echo '$var = '; echo $var; echo "<br>"; echo 'intval($var) = '; echo intval($var); echo "<br>"; On PHP 5.2.1, it returns : var_dump($var) = float(-2302452860) $var = -2302452860 intval($var) = -2147483648 On PHP 5.1.6, it returns : var_dump($var) = float(-2302452860) $var = -2302452860 intval($var) = 1992514436 Is there anyway to get, in any case, the truncated result ? Any php.ini parameter ?
