real

 

 

Description

The real function returns the real part of the complex argument of the function.

When to use

The real function is used to extract the real part of a complex number.

 

Syntax

(real X)

Name Description AIS Types
XA complex number.Complex

Returns:

A real number holding the real part of its argument.

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_Complex_real_001

Extracting the real part of a complex value using the real function is shown in the example below.

 

Argument Types

Here are the links to the data types of the function arguments.

Complex

Here are also a number of links to functions having arguments with any of these data types.
