Complex numbers are concatenated versions of floating-point numbers with a real and an imaginary part. Refer to the Numeric Data Types Table for more information about numeric data type bits, digits, and range. There are three types of complex numbers.

Complex single-precision, floating-point (CSG) —Same as single-precision, floating-point for each (real and imaginary) part.
Complex double-precision, floating-point (CDB) —Same as double-precision, floating-point for each (real and imaginary) part.
Complex extended-precision, floating-point (CXT) —Same as extended-precision, floating-point for each (real and imaginary) part.

Use the Complex functions to create complex numbers.
