The Criterion for Expressing Errors with Significant Digit

Abstract:

This paper, based on the tiny error rule (TER) in algebraic sum method, derived the criterion for correctly expressing errors with significant digit, for the first time. Then, according to the criterion, an important conclusion is further reached, namely, any error only needs to keep three significant digits at most, or it is meaningless. Thus, this paper further perfected the theory of error, and so, it is of great significance for accurately processing all measurement data.
