Complex numbers

In Perl 6, there is the Complex built-in type to present complex numbers.

Complex numbers have two parts, real and imaginary, and use the following syntax:

my $x = 3+4i;
my $y = -5i;

It is not necessary to explicitly spell out the real part, but the output always contains it:

say $x; # 3+4i
say $y; # -0-5i
say $z; # 0+1i

An alternative way to create a Complex number is to call a constructor (we will talk about constructors in Chapter 8, Object-Oriented Programming), as follows:

my $n = Complex.new(4, 5);
say $n; # 4+5i
