Converts an object to a complex number.
Xis any object
X is any number, then
X as an object of type
X is a vector, matrix, list, set, or structure – in each case containing only a single element which is a number – then this number is returned in the form of a complex number object.
X is an real two-dimensional vector, the natural mapping between ℝ² and ℂ is used to map
(x, y) into
x + y⋅i.
X is a string, an attempt is made to parse it as a complex number. If successful, the parsed number is returned.
In all other cases,
ComplexNumber(X) returns an error.
