Integer comparison

my $a = prompt("1st int: ").floor;
my $b = prompt("2nd int: ").floor;

if $a < $b {
    say 'Less';
}
elsif $a > $b {
    say 'Greater';
}
elsif $a == $b {
    say 'Equal';
}

With <=>:

say <Less Equal Greater>[($a <=> $b) + 1];

A three-way comparison such as <=> actually returns an Order enum which stringifies into 'Decrease', 'Increase' or 'Same'. So if it's ok to use this particular vocabulary, you could say that this task is actually a built in:

say prompt("1st int: ") <=> prompt("2nd int: ");
