    Computes the sum of the inputs.

    You cannot add two timestamp values together.

    input

    An input to this operation.

    This input supports scalar numbers, arrays or clusters of numbers, arrays of clusters of numbers, timestamps, or waveforms.

    Data Type Changes on FPGA

    When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

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

    This input appears only when you wire a waveform to input.

    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.

    sum

    The sum of the inputs.

    When you add this node to a document targeted to an FPGA, this output has a default data type that uses fewer hardware resources at compile time.

    error out

    The node produces this output according to standard error behavior.

    This output appears only when you wire a waveform to input.
