Re: Re: Re: hex(unpack("H*")) help?!?!

Ah. OK. Is the string always two chars long?

$number = hex("0x". reverse $string);

I think you need to do some reading. reverse doesn't work how you think either... reverse "ab" is "ab" ... sorry.	[reply]

Er... the result of `reverse "ab"` varies according to the context it is evaluated in. The concaternation operator evaluates it in scalar context. `$ perl -le 'print "0x" . reverse "ab"' 0xba` [download] I'm not saying my solution is a good idea, but I do know how `reverse` works :) -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply] [d/l]
