ComplexNumber
Converts an object to a complex number.
Syntax

ComplexNumber(X)

X
is any object

Description
If X
is any number, then ComplexNumber(X)
returns X
as an object of type ComplexNumber
.
If 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.
If X
is an real twodimensional vector, the natural mapping between ℝ² and ℂ is used to map (x, y)
into x + y⋅i
.
If 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.
Examples
'((n ≔ 687), (x ≔ ComplexNumber(n))) @ type
integer complex number
ComplexNumber(❨❨5, 9, 3, 1❩❩ ⋅ ❨❨7❩, ❨2❩, ❨4❩, ❨i❩❩)
65 + i
'("7 + 3⋅i", "−5.2E−4 + 3.6j", "−.4 − .8⋅i", "i−2.5E3") @ ComplexNumber
7 + 3⋅i −0.00052 + 3.6⋅i −0.4 − 0.8⋅i −2500 + i
