Re: Re: passing hex argument as string

yes I am familiar with printf function. But I can not do that. Beccause the function that takes $chr is *FIXED*, and I can not change it. So what I want is a function that: # takes a hex number 0xff # returns string "ff" and NOT 255

That's what `sprintf("%x", $hexnum)` [download] does. If $hexnum is 0xdeadbeef, the sprintf will return "deadbeef". (Use %X instead of %x if you want "DEADBEEF".) (updated to correctly say sprintf instead of printf)	[reply] [d/l]
