• Sending awkward characters by email in Perl - [link]

Source code: fprint Module: P207

@names = qw(Andrew Barbara Chloe Dan Elizabeth Flossie);

$gift = 100;
$kiddo = 15;

for ($k=1; $k<=$kiddo; $k++) {
        $gets = $gift / $k;
        $called = $names[$k % @names];
        printf "Add %7s. With %06b in favour, each gets %8.2f\n",$called,$k,$gets;
        }

__END__

%....[lower case letter]
b o d x - INTEGER - Binary, Octal, Decimal, Hexadecimal
f e g - FLOAT - float, exponentoial, 'general'
c s - Individual character, character string
(General format - whichever of e and f is most sensible!)
(This is perl - lots of other obscure ones too!)

%-8.3f
Floating point value
3 characters after the decimal place
A TOTAL of 8 characters minimum (NOT 8 before the decimal)
- sign means "left justified" (and a lead zero would zero fill)
