Also when <br /> recording general mineral data use three significant figures to allow for the anion and cation balance <br /> calculation. <br /> Significant Figure Examples: <br /> Raw Result Reported result <br /> 0.0001 0.00002849 ND <br /> 0.0001 0.0002849 0.0003 <br /> 0.0001 0.002849 0.0028 <br /> 0.0001 0.02849 0.028 <br /> 0.0001 0.2849 0.28 <br /> 1 0.2849 ND <br /> 1 2.849 3 <br /> 1 28.49 28 <br /> 1 284.9 280 <br /> 1 2849 2800 <br /> 5.7 Evans rule is used for data rounding. If the value ends in exactly 5 you round up if the resulting <br /> number becomes even. Round down if the resulting number becomes odd. When the value does not <br /> end in exactly 5 use normal rounding rules. Any result under the detection limit is reported as ND <br /> unless specifically requested in a project and qualified in the deliverables. For example a result of 0.99 <br /> with a detection limit of 1 is reported as ND. When calculations are performed on DLR's and data <br /> round the results after the calculations are performed. <br /> Rounding Examples for DLR of 1 <br /> Raw Result Reported result <br /> 28.49 28 <br /> 28.5 28 <br /> 28.51 29 <br /> 29.49 29 <br /> 29.5 30 <br /> 29.51 30 <br /> 5.8 Remarks for reporting should be written on the worksheet and noted to include on the final report. <br /> These notes should be reviewed by the person performing the release of the data for proper use of <br /> grammar, spelling, technical content and clarity. <br /> -6.0 Record Storage and Archiving: N/A <br /> 7.0 References: N/A <br /> 8.0 Associated Documents: N/A <br /> 9.0 Record of Major Revisions: <br /> None at this time <br />
