By definition, flood waters have been in contact with the ground, so as I read OP and subject to clarification, I agree that this would not be "rainwater" for purity considerations. Even if it were water that got into a building from above, unless there was a gaping hole in the roof, the water probably passed through some building materials that would leave unsavory deposits on your electronics.

Considering the quality of the air that the rain passes through going from cloud to ground, probably so.
