For your computer 0xffffff85 is -123 and 4294967173. It's just how you look on it. > So after more thinking, I figure when upgrading dec*() to handle any > number, absolute value should be used (then int(123) would be > returned in my example).

Why should hexdec(dechex(-123)) return +123? -- Michael -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
