NPrecision

Accuracy

FilledSmallSquareAccuracy[x] gives the number of digits to the right of the decimal point in the number x.

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

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

FilledSmallSquareAccuracy assumes a precision of $MachinePrecision when applied to machine-precision numbers.

FilledSmallSquareAccuracy can yield a negative result.

FilledSmallSquare See The Mathematica Book: Section 3.1.4.
