There are several ways.
1. You can use the new 'say' function, instead of 'print', which automatically
adds a newline to every output. Put 'use feature say' at the beginning of your
program:
say pi * 2;
2. You can print a list:
print pi * 2, "\n";
3. You can concatenate a newline onto the end of your string:
print pi * 2 . "\n";
4. You can use the printf function:
printf "%f\n", pi * 2
