Icon doesn't provide native support for complex numbers. Support is included in the IPL.
Note: see the [[Arithmetic/Complex#Unicon|Unicon]] section below for a Unicon-specific solution.

Note that the parentheses around ∠ notation are required. It has a related use in vectors: (1∠π/4) is a complex number, [1,∠π/4] is a vector in two dimensions in polar notation, and [(1∠π/4)] is a complex number in a vector.
=={{header|Unicon}}==
Takes advantage of Unicon's operator overloading extension and Unicon's Complex class. Negation is not supported by the Complex class.
