Polybench® Reference
Captures a constant value and issues an action with the constant value if the value changes.

Constant To Action


This operator performs an Action (link) as soon as a constant floating point value changes at the input. The input value is captured and used as Value for the action.
Like the Capture Action operator (link), this operator provides an interface from signal processing to program control.

Input K: Floating point values

type: Select from the list
Select the code of the Action that is performed when the constant value at the input changes.
Select one of those presets:

type: See description [this value cannot be changed]
The value of the Action is the new constant value at the input of the operator.

type: Address, starts with '$' sign (see link)
Fill in the address of the object that should receive the Action.

You may type or paste the address, or you may press the small button on the right to open the Address Searcher dialog (link)

type: See description
The way the captured value is represented as value in the specified Action, e.g.: '.1' for one digit and a decimal point, or '>,3' for a value with at most three digits and a decimal comma.

For more information about Number Format codes, please refer to link.

type: Word or phrase
The name of the object in the project. This name must not contain '.' or '$' characters.

Every object has the Caption property. This property is very important, because it is the name by which Polybench recognizes this object.
It is allowed to give multiple objects the same name, as long as the objects are of the same type. In that case, a reference to this caption includes all the objects with the same caption.
In Polybench, every object can be addressed by an Address specifier, which starts with the dollar sign, for example: $My Page.My Object. 'My Page' would be the Caption of a page, and 'My Object' the Caption of an object on that page.

type: See description
Optional documentation of this object.

It is good practice to write in short notes why you have used this object, and why its properties are set the way they are set. If this object is an operator, the Documentation text is displayed below the operator symbol.


The connection to the input of this operator must be of type Constant, must have only one channel, and must be of floating point type. The operator warns if the input conditions are not met.
