Sort[list, p]

DetailsDetails

  • Sort by default orders integers, rational, and approximate real numbers by their numerical values.
  • Sort orders complex numbers by their real parts, and in the event of a tie, by the absolute values of their imaginary parts.
  • Sort orders symbols by their names, and in the event of a tie, by their contexts.
  • Sort usually orders expressions by putting shorter ones first, and then comparing parts in a depth-first manner.
  • Sort treats powers and products specially, ordering them to correspond to terms in a polynomial.
  • Sort orders strings as in a dictionary, with uppercase versions of letters coming after lowercase ones. Sort places ordinary letters first, followed in order by script, Gothic, double-struck, Greek, and Hebrew. Mathematical operators appear in order of decreasing precedence.
  • Sort[list, p] applies the function p to pairs of elements in list to determine whether they are in order. The default function p is OrderedQ[{#1, #2}]&.
  • Sort can be used on expressions with any head, not only List.
