DepthFirstScan (Built-in Mathematica Symbol)

DepthFirstScan[g, s, {"event_1" -> f_1, "event_2" -> f_2, ...}] performs a depth-first scan of the graph g starting at the vertex s and evaluates f_i whenever "event_i" ...

DiscreteDelta (Built-in Mathematica Symbol)

DiscreteDelta[n_1, n_2, ...] gives the discrete delta function \[Delta] (n_1, n_2, ...), equal to 1 if all the n_i are zero, and 0 otherwise.

DistributionParameterQ (Built-in Mathematica Symbol)

DistributionParameterQ[dist] yields True if dist is a valid distribution, and yields False otherwise.

Divisible (Built-in Mathematica Symbol)

Divisible[n, m] yields True if n is divisible by m, and yields False if it is not.
