error preservation

Error preservation refers to the property of a computational system or algorithm that ensures the correctness of data or results remains intact throughout various transformations or processes. In simple terms, it means that if there's a mistake or error in the original data, the process won't accidentally fix or hide it, and if the data is correct, the process won't introduce new errors. This concept is important in ensuring the integrity and reliability of calculations, data transmission, and processing, so that the outcome accurately reflects the original information without unintended alterations.
