Data Type Reference
You can use the following data types for controls and indicators, diagram terminals, wires, and node terminals.
| Icon | Data Type | Details |
|---|---|---|
|
Single-precision, floating-point numeric (SGL) |
Minimum positive number: 1.40e-45 Maximum positive number: 3.40e+38 Minimum negative number: -3.40e+38 Maximum negative number: -1.40e-45 |
|
Double-precision, floating-point numeric (DBL) |
Minimum positive number: 4.94e-324 Maximum positive number: 1.79e+308 Minimum negative number: -1.79e+308 Maximum negative number: -4.94e-324 |
|
Complex single-precision, floating-point numeric (CSG) | Same as single-precision, floating-point, with a real and an imaginary part. |
|
Complex double-precision, floating-point numeric (CDB) | Same as double-precision, floating-point, with a real and an imaginary part. |
|
8-bit signed integer numeric (I8) |
A positive or negative integer stored using 8 bits, or a single byte. Range: -128 to 127 |
|
16-bit signed integer numeric (I16) |
A positive or negative integer stored using 16 bits, or two bytes. Range: -32,768 to 32,767 |
|
32-bit signed integer numeric (I32) |
A positive or negative integer stored using 32 bits, or four bytes. Range: -2,147,483,648 to 2,147,483,647 |
|
64-bit signed integer numeric (I64) |
A positive or negative integer stored using 64 bits, or eight bytes. Approximate Range: -1e19 to 1e19 |
|
8-bit unsigned integer numeric (U8) |
A positive integer stored using 8 bits, or a single byte. Range: 0 to 255 |
|
16-bit unsigned integer numeric (U16) |
A positive integer stored using 16 bits, or two bytes. Range: 0 to 65,535 |
|
32-bit unsigned integer numeric (U32) |
A positive integer stored using 32 bits, or four bytes. Range: 0 to 4,294,967,295 |
|
64-bit unsigned integer numeric (U64) |
A positive integer stored using 64 bits, or eight bytes. Approximate Range: 0 to 2e19 |
|
timestamp |
A time and date. Minimum time: 01/01/1600 00:00:00 UTC maximum time: 01/01/3001 00:00:00 UTC |
|
enumerated type | A list of items from which to select. |
|
Boolean | A TRUE/FALSE value. |
|
string | A series of text characters. |
|
array |
A collection of multiple pieces of data, each of which must be the same data type. The array icon shows the data type of the array's elements in square brackets and takes the color of that data type. As you add dimensions to the array, the thickness of the output wire increases. |
|
cluster |
A collection of multiple pieces of data, each of which can be a different data type. Cluster data types appear brown if all elements in the cluster are numeric or pink if any elements in the cluster are of non-numeric types. |
|
error cluster |
A cluster of information that specifies error conditions returned by a node. |
|
path |
The location of a file or directory. |
|
waveform |
A cluster of information that specifies an array of data, the start time at which the data was collected, and the change in time between each measurement. |
|
digital waveform |
A cluster of information that specifies a digital table of data, the start time at which the data was collected, and the change in time between each measurement. |
|
reference number (refnum) |
A unique identifier for an object, such as a file or a task. |
|
variant |
A generic container for all other types of data. |
