From Real
(Real) method Real
Defined as:
multi method Real(Real: --> Real)multi method Real(Real: --> Real)
The :D
variant simply returns the invocant. The :U
variant issues a warning about using an uninitialized value in numeric context and then returns self.new
.
class Complex
From Complex
(Complex) method Real
Defined as:
multi method Real(Complex: --> Num)multi method Real(Complex: --> Num)
Coerces the invocant to Num. If the imaginary part isn't approximately zero, coercion fails with X::Numeric::Real
.
The :D
variant returns the result of that coercion. The :U
variant issues a warning about using an uninitialized value in numeric context and then returns value 0e0
.
class ComplexStr

(ComplexStr) method Real
Defined as:
multi method Real(ComplexStr: --> Num)multi method Real(ComplexStr: --> Num)
Coerces the numeric portion of the invocant to Num. If the imaginary part isn't approximately zero, coercion fails with X::Numeric::Real
.
The :D
variant returns the result of that coercion. The :U
variant issues a warning about using an uninitialized value in numeric context and then returns value 0e0

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
.
