class DemoSubPub : public Node

A demonstration of a simple ROS2 node that raises numbers to a power and root

This node is used as a demo of how to setup a folder for a package, including various things like documentation and testing. The node itself listens to a custom message that contains a number and an exponent, then publishes a message with the number taken to the power and root of that exponent.

Topics Subscribed: /num_power (fqdemo_msgs.msg.NumPwrdata). Publishes a message to /power_result after message is received.

Topics Published: /power_result (fqdemo_msgs.msg.NumPwrResult). A zero-valued message is published periodically. A message with appropriate values is published in response to a /num_power message.
