thank you for the tips, one question though

I don't quite understand this line:

my $phiApprox = $fibNum <= 1 ? '***' : $fibValue1 / $fibValue2;

In paticular this part:

 ? '***' :

Obviously it makes $phiApprox = '***' when $fibNum is <= 1, else it performs the arithmatic. But I don't really understand why, I would never have thought of that code.
