What is 0.0 in chess?

Could you please clarify what you mean by "0.0" in chess? In chess, we typically use terms like "checkmate," "pawn," "king," and other game-related vocabulary. If you're referring to a specific chess notation or term that's unfamiliar to me, could you provide more context or an example? Alternatively, if you're asking about a rating or score of some sort, it's worth noting that chess ratings and scores are typically expressed as numbers, but "0.0" as a standalone expression doesn't immediately come to mind in the context of chess. Perhaps you could elaborate on what you're referring to?
