Round (Built-in Mathematica Symbol)

Round[x] gives the integer closest to x. Round[x, a] rounds to the nearest multiple of a.

Tolerance (Built-in Mathematica Symbol)

Tolerance is an option for various numerical options which specifies the tolerance that should be allowed in computing results.

NSeries (Numerical Calculus Package Symbol)

NSeries[f, {x, x_0, n}] gives a numerical approximation to the series expansion of f about the point x = x_0 including the terms (x - x_0) -n through (x - x_0) n.

Radius (Numerical Calculus Package Symbol)

Radius is an option to NSeries that specifies the radius of the circle around which the function is to be sampled.

Accuracy (Built-in Mathematica Symbol)

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

Cross (Built-in Mathematica Symbol)

Cross[a, b] gives the vector cross product of a and b.
