Complex numbers are concatenated versions of floating-point numbers with a real and an imaginary part. Labview includes CSG, CDB, and CXT floating-point numeric data types.

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.

LabVIEW control terminal representing a complex single-precision, floating-point number. Complex single-precision, floating-point (CSG) —Same as single-precision, floating-point for each (real and imaginary) part.
LabVIEW control terminal representing a complex double-precision floating-point numeric data type. Complex double-precision, floating-point (CDB) —Same as double-precision, floating-point for each (real and imaginary) part.
LabVIEW control terminal representing a complex extended-precision floating-point numeric data type. 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.
