FilledSmallSquare DiracDelta[x] represents the Dirac delta function .

FilledSmallSquare DiracDelta[, , ... ] represents the multidimensional Dirac delta function .

FilledSmallSquare DiracDelta[x] returns 0 for all numeric x other than 0.

FilledSmallSquare DiracDelta can be used in integrals, integral transforms and differential equations.

FilledSmallSquare Some transformations are done automatically when DiracDelta appears in a product of terms.

FilledSmallSquare DiracDelta[, , ... ] returns 0 if any of the are numeric and not 0.

FilledSmallSquare DiracDelta has attribute Orderless.

FilledSmallSquare For exact numeric quantities, DiracDelta internally uses numerical approximations to establish its result. This process can be affected by the setting of the global variable $MaxExtraPrecision.
