Rounding To round the error of a quantity with uncertainty, use the ApplyR-
ule command. For a description of the predefined rounding rules, refer to
the ?ScientificErrorAnalysis/rules help page.
>
Units Quantities with errors can have units. For example, the scientific
constants and element (and isotope) properties in the ScientificConstants
packages are quantities with errors and units.
To construct a new quantity with units and an uncertainty, include units in
the Quantity calling sequence.
For an absolute error, you must specify the units in both the value and error.

>
For a relative error, you can specify the units in only the value.
