AccuracyGoal is an option for various numerical operations which specifies how many effective digits of accuracy should be sought in the final result.

AlgebraicIntegerQ[a] yields True if a is an algebraic integer, and yields False otherwise.

BarnesG[z] gives the Barnes G-function G(z).

GridCreationSettings -> {opt_1 -> val_1, opt_2 -> val_2, ...} is a global option that specifies settings for the Create Table/Matrix dialog.

SeriesData[x, x_0, {a_0, a_1, ...}, n_min, n_max, den] represents a power series in the variable x about the point x_0. The a_i are the coefficients in the power series. The ...
