Note: The paper Jorgen L. Nikolajsen, FRACTIONAL SIGNIFICANT DIGITS, SIAM J. Sci. Comput., 35 (2), A561-A576 discusses how to eliminate the ambiguities in how signifcant digits are defined and gives a procedure for calculating the number of significant digits with the same accuracy as absolute and relative errors.
