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

BarabasiAlbertGraphDistribution[n, k] represents a Barabasi\[Dash]Albert graph distribution for n-vertex graphs where a new vertex with k edges is added at each step.

Complex is the head used for complex numbers.

Nand[e_1, e_2, ...] is the logical NAND function. It evaluates its arguments in order, giving True immediately if any of them are False, and False if they are all True.

Nor[e_1, e_2, ...] is the logical NOR function. It evaluates its arguments in order, giving False immediately if any of them are True, and True if they are all False.

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

TimeValue[s, i, t] calculates the time value of a security s at time t for an interest specified by i.
