- ## Method Details

  - ### initThreads

    protected void initThreads(Container container, GridBagConstraints constraints)
    Description copied from class: `PiAWT`
    Initialize the "threads" section GUI elements. Elements should be added for the remainder of the width of the `container`.
    Overrides:
      `initThreads` in class `PiAWT`

      `container` - The container where the elements are to be added.
      `constraints` - The constraints with which the elements are to be added to the `container`.

  - ### isInputValid

    protected boolean isInputValid()
    Description copied from class: `PiAWT`
    Validates the input fields.
    Overrides:
      `isInputValid` in class `PiAWT`
    Returns:
      `true` if all input fields contain valid values, otherwise `false`.

  - ### getOperation

    protected Operation<Apfloat> getOperation(long precision, int radix) throws ApfloatRuntimeException
    Description copied from class: `PiAWT`
    Get the calculation operation to execute.
    Overrides:
      `getOperation` in class `PiAWT`
    Parameters:
      `precision` - The precision to be used.
      `radix` - The radix to be used.
    Returns:
      The calculation operation to execute.
    Throws:
      `ApfloatRuntimeException`
