    Substitutes a formula string by given rules.

    connector_pane_image
    datatype_icon

    formula

    Formula that this node uses to substitute variables.

    datatype_icon

    substitution rules

    Rules for substituting variables.

    datatype_icon

    parameter name

    Name of the parameter that this node looks for in formula.

    parameter name can contain any number of valid characters. If parts of the original string represent numbers like 1E-2, the parameter name cannot begin with capital letter E. Otherwise, this node produces unpredictable errors.

    datatype_icon

    parameter content

    Content of the parameter. parameter content must have a one-to-one relation with parameter name.

    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

    formula after substitution

    Final formula after all substitution rules are performed.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
