There Seems To Be Uncertainty about the Use of Significant Figures in Reporting Uncertainties of Results

Abstract
A cursory review of two journals indicates that uncertainties in experimental results are not consistently reported in the literature with the correct number of significant figures. The problem seems more frequent in computer generated results in both chemical education and research articles. Examples of published values with uncertainty inappropriately reported are included along with the appropriate rounding.
