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

FilledSmallSquare AccuracyGoal is an option for such functions as NIntegrate, NDSolve and FindRoot.

FilledSmallSquare AccuracyGoal -> Automatic normally yields an accuracy goal equal to half the setting for WorkingPrecision.

FilledSmallSquare AccuracyGoal -> Infinity specifies that accuracy should not be used as the criterion for terminating the numerical procedure. PrecisionGoal is typically used in this case.

FilledSmallSquare Even though you may specify AccuracyGoal->n, the results you get may sometimes have much less than n-digit accuracy.

FilledSmallSquare In most cases, you must set WorkingPrecision to be at least as large as AccuracyGoal.

FilledSmallSquare AccuracyGoal effectively specifies the absolute error allowed in a numerical procedure.

FilledSmallSquare With AccuracyGoal->a and PrecisionGoal->p, Mathematica attempts to make the numerical error in a result of size be less than .

FilledSmallSquare See Section 3.9.4 and Section 3.9.9.
