The Double Node
The Double node () declares one or more named scalar double floating-point values that you can access from form objects and methods. You can use a double as a source in some input that is a floating-point number (some scalar value). The Settings window contains the following section.
List of Variables
This section contains a single table, where you specify one double stored per row. Specify the name in the Name column and the initial value in the Initial value column (the default is 0.0). You can also add an optional description of the double in the Description column.
Although you can specify the initial value for a double, that value may be overwritten if you use the double as a source to a form object that specifies a different value.
Use the Move Up (), Move Down (), Insert Above (), and Delete () toolbar buttons to organize and remove choices from the list.
Code Access
In the code of a method, you access a double named dbl1 as if it were a normal Java double variable:
double d = dbl1;
dbl1 = newValue;
