Decrement (Built-in Mathematica Symbol)

x-- decreases the value of x by 1, returning the old value of x.

Defer (Built-in Mathematica Symbol)

Defer[expr] yields an object that displays as the unevaluated form of expr, but that is evaluated if it is explicitly given as Mathematica input.

DirichletConvolve (Built-in Mathematica Symbol)

DirichletConvolve[f, g, n, m] gives the Dirichlet convolution of the expressions f and g.

DirichletTransform (Built-in Mathematica Symbol)

DirichletTransform[expr, n, s] gives the Dirichlet transform of expr with respect to n.

DistanceFunction (Built-in Mathematica Symbol)

DistanceFunction is an option for functions such as Nearest that specifies the distance value to assume between any two specified points.

DistributeDefinitions (Built-in Mathematica Symbol)

DistributeDefinitions[s_1, s_2, ...] distributes all definitions for the symbols s_i to all parallel kernels.DistributeDefinitions["context"] distributes definitions for all ...

DynamicWrapper (Built-in Mathematica Symbol)

DynamicWrapper[e, expr] represents an object that displays as e, but dynamically updates the expression expr whenever that object is visible on screen.

EllipticTheta (Built-in Mathematica Symbol)

EllipticTheta[a, u, q] gives the theta function \[CurlyTheta]_a (u, q) (a = 1, ..., 4).

EmptyGraphQ (Built-in Mathematica Symbol)

EmptyGraphQ[g] yields True if g is an empty graph and False otherwise.

Enabled (Built-in Mathematica Symbol)

Enabled is an option for objects such as Slider that specifies whether the objects should be enabled for interactive manipulation.
