Complex Number Operator (FPScript)
Combines a real part and an imaginary part into a complex number.
Syntax
(RealPart, ImaginaryPart)
The syntax of the ( , ) operator consists of the following elements:
Element |
Description |
|---|---|
RealPart |
A real numeric expression or a string with the real part. |
ImaginaryPart |
A real numeric expression or a string with the imaginary part. |
Remarks
The operator can process scalar values or entire data series and data matrices. If at least one argument is a data series or a data matrix, then the bundling takes place on a per-element basis and the result is once again a data series or a data matrix. If signals, signal series or space curves are combined, only their Y components are examined. The result then preferably contains the X component and possibly the Z component of Real part. Otherwise, it contains those of Imaginary part. If one of the expressions returns a list, then the operation is executed for each item in the list and the result is also a list.
If one argument is numeric and the other is a string, the string is changed to the numeric type before the operation. Both arguments cannot be strings.
If Real part and ImaginaryPart is a quantity, then they have to have the same SI dimension and the unit of ImaginaryPart is transformed to the unit of RealPart before being combined to become a complex number. If only one argument is a quantity, then the same unit is used for the other argument.
Note: Instead of this operator, you can also use the imaginary unit i to create complex numbers.

Examples
(1, 2.) |
Generates the complex 64-bit floating point scalar value (1.,2.). |
1 + 2.i |
Same as the previous example. |
(1n, 2L) |
Generates the complex 64-bit integer scalar value (1L, 2L). |
({1, 2., 4}, 0) |
Generates a data series with three complex 64-bit floating point values. All imaginary parts are 0. |
(DataMatrix, DataSeries) |
Generates a data matrix with complex values. All columns have the same imaginary parts. |
(1 V, 200 mV) |
Generates the complex 64-bit floating point quantity (1 V, 0.2 V). |
