Perl: Confusion About A Little Piece Of Code

Hi,
Maybe I'm not understanding this. Here is some code.
print "Enter some numbers on separate lines: ";
my $user_total = total(<STDIN>);
I'm pretending that there's a subroutine that adds up the numbers.
I'm thinking that I would enter the numbers from the keyboard on separate
lines, and when I'm done, I'd press the key combination that signals end of
input.
When the program gets the array, I'm thinking that each line would have a new
line on the end of it.
Here's where the question comes in.
Would the subroutine need to use the chomp function to get rid of the new lines
before it adds up the numbers, or would it be happy with the line endings?
Thanks.
Jim
