ComplexConstant

A complex literal.

Declaración

Sintaxis

ComplexConstant(float re, float im, ttype type)

Argumentos

Argument

Descripción

re

the real part.

im

the imaginary part.

type

the complex type, which fixes the kind.

Valores devueltos

The value of the expression.

Descripción

Both parts are stored as numbers. A complex literal whose parts are not both constants is a ComplexConstructor instead.

Ejemplos

(ComplexConstant
  :re 1.0
  :im 2.0
  :type (Complex
    :kind 4
  )
)
