DetailsDetails

  • An expression is considered a numeric quantity if it is either an explicit number or a mathematical constant such as Pi, or is a function that has attribute NumericFunction and all of whose arguments are numeric quantities.
  • In most cases, NumericQ[expr] gives True whenever N[expr] would yield an explicit number.
