Here is an example for "raw" reading of Float variables.It could be very useful ,when loading data from files or network sockets. $bytestring = "\xC2\xE2\xA0\x00"; //this is the binary representation of the number "-113.3125" function getfloat ($bytes) { $bits = 0; $len = strlen($bytes); if($len == 4){ $explen = 8 ; $mantisa = 23; for($n=0;$n<$len;$n++){ $bits |= (ord($bytes[$n]) << ($len-$n-1)*8); } } else if($len == 1){ $explen = 3; $mantisa = 4; $bits = ord($bytes[0]); } else {return false;} if ($bits & (1 << ($mantisa + $explen))) {$out = "-";} $stepen = ((((pow(2,$explen)-1) << $mantisa) & $bits) >> $mantisa) - pow(2,$explen-1) + 1 ; $ednocqloi = (pow(2,$mantisa)-1) & $bits ; $out .= (1 + $ednocqloi/pow(2,$mantisa)) * pow(2,$stepen) ; return $out ; } if(!$floatvar = getfloat($bytestring)) {echo "invalid byte/word";} else {echo $floatvar;} -- http://www.php.net/manual/en/language.operators.bitwise.php http://master.php.net/manage/user-notes.php?action=edit+25404 http://master.php.net/manage/user-notes.php?action=delete+25404 http://master.php.net/manage/user-notes.php?action=reject+25404
