Convert characters to hex values in perl

pjz · 12-07-2005, 02:18 PM

I'm using Red Hat 9.0.

This is a perl programming question.

I'm opening up a file that consists of a series of
bytes. I'd like to be able to deal with the character
stream as a series of hex values, not as characters.

Is there any way that I can convert a character into it's hex equivalent. In C, I can use the function
atoi(). I'd like to know if Perl supplies anything
like this function.

thanks

printf() with x as the format specifier....

According to the Camel book, its:
sprintf("%lx", $num); # that's a lowercase 'L', not a one (1)

Found the answer. Thanks big to those who replied.

The way to do this is:

$foo = ord($bar);

where $bar is a character, and $foo is a number.
