FilledSmallSquarePrecision[x] gives the number of digits of precision in the number x.

FilledSmallSquare If x is not a number, Precision[x] gives the minimum value of Precision for all the numbers that appear in x.

FilledSmallSquarePrecision gives Infinity when applied to exact numbers, such as integers.

FilledSmallSquarePrecision gives $MachinePrecision for machine-precision numbers.

FilledSmallSquare See The Mathematica Book: Section 3.1.4.
