isComplex

 

 

Overview

The isComplex function returns a Boolean which is true if, and only if, its argument is Complex.

Usage

The isComplex function is used to test the data type of an argument to determine if it is complex.

 

Syntax

Expression:

(isComplex X)

Arguments Name Type Description
Argument:X Character String Symbol Vector BitVector ByteVector IntVector Void FltVector ObjVector Structure Dictionary Directory Brick Pair List ObjectRepository Matrix NumMatrix Integer Float Number Complex Boolean Date Function Any Lisp data type.

Returns:

The Boolean, true if X is a complex number; else, returns false.

 

Examples
