Are values rounded? How does MPD decide what level of numeric precision to present?
When MPD accessions numeric data, each value is automatically rounded to a certain precision based on the magnitude of the individual number. In order to avoid loss of information the rounding algorithm often provides a bit more precision than is necessary. This method sometimes results in different precisions for two similar numbers when one is over and the other under a certain magnitude cutoff. MPD does not attempt to control the degree of numeric precision on a measurement-by-measurement basis, therefore the MPD-displayed precision may not be the same as the precision produced by a given laboratory apparatus, or as supplied by an investigator.
