class IntStr is Allomorph is Int { }

IntStr is a dual value type, a subclass of both Allomorph, hence Str, and Int.

See Allomorph for further details.

my $int-str = <42>;
say $int-str.^name;     # OUTPUT: «IntStr␤» 
 
my Int $int = $int-str# OK! 
my Str $str = $int-str# OK! 
 
# ∈ operator cares about object identity 
say 42  <42  55  1>;   # OUTPUT: «False␤» 

Methods§

method new§

method new(Int $iStr $s)

The constructor requires both the Int and the Str value, when constructing one directly the values can be whatever is required:

my $f = IntStr.new(42"forty two");
say +$f# OUTPUT: «42␤» 
say ~$f# OUTPUT: «"forty two"␤»

method Int§

method Int

Returns the integer value of the IntStr.

method Numeric§

multi method Numeric(IntStr:D: --> Int:D)
multi method Numeric(IntStr:U: --> Int:D)

The :D variant returns the numeric portion of the invocant. The :U variant issues a warning about using an uninitialized value in numeric context and then returns value 0.

method Real§

multi method Real(IntStr:D: --> Int:D)
multi method Real(IntStr:U: --> Int:D)

The :D variant returns the numeric portion of the invocant. The :U variant issues a warning about using an uninitialized value in numeric context and then returns value 0.

Operators§

infix ===§

multi sub infix:<===>(IntStr:D $aIntStr:D $b)

IntStr Value identity operator. Returns True if the Int values of $a and $b are identical and their Str values are also identical. Returns False otherwise.
