Retrieves enumeration, unit, and representation information from a variant that contains a numeric data type.

This node returns an error if the variant does not contain a numeric.

datatype_icon

variant

Variant data from which you want to retrieve data type information.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

enum names

Enumerated values, if the numeric data type stored in the variant is an enumeration. Otherwise, this output returns an empty string.

datatype_icon

units

Unit type and exponent, if the numeric data type stored in the variant has units.

datatype_icon

Unit Type

Unit type of the numeric data type stored in the variant.

Name Description
Radians The numeric data type has a unit type of radians.
Steradians The numeric data type has a unit type of steradians.
Seconds The numeric data type has a unit type of seconds.
Meters The numeric data type has a unit type of meters.
Kilograms The numeric data type has a unit type of kilograms.
Amperes The numeric data type has a unit type of amperes.
Kelvins The numeric data type has a unit type of kelvins.
Moles The numeric data type has a unit type of moles.
Candelas The numeric data type has a unit type of candelas.
InvalidUnit The unit type of the numeric data type is invalid.
datatype_icon

Exponent

Exponent of the unit.

datatype_icon

representation

Numeric representation of the data type stored in the variant.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
