NumberMarks

NumberMarks is an option for InputForm and related functions that specifies whether ` marks should be included in the printed forms of approximate numbers.

The default setting for NumberMarks is given by the value of $NumberMarks.

NumberMarks->True indicates that ` should be used in all approximate numbers, both machine-precision and arbitrary-precision ones.

NumberMarks -> Automatic indicates that ` should be used in arbitrary-precision but not machine-precision numbers.

NumberMarks -> False indicates that ` should never be used in outputting numbers.

Number marks are used to indicate the type of numbers, and their precision or accuracy.

The *^ form for scientific notation is always used in InputForm, and is independent of NumberMarks.

See Section 2.12.3 and Section 3.1.4.
