The Calculator component API consists of the following methods:
-
getString("expression"), set("expression", myExpression).
This method allows you to get/set the value of the expression as a string.
When setting the value of an expression, this method overwrites the previous
value.
-
add("calculation", oneCalculation). This method adds
a new calculation to the end of the current expression.
After you call the set() or add() methods,
you must call the apply() method to store the new expression
in the Calculator component. The new expression can contain undefined
parameters. Calling the apply() method adds these undefined
parameters to the component with suitable mode, data type, and dimensions
(for arrays).
The expression can request additional functions if it contains a line
that starts with '#import' followed by the Library name
of the plug-in that defines the functions.
