sorts the elements of list into canonical order.
sorts using the ordering function p.
- 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 ordering function p to pairs of elements in list to determine whether they are in order. The default function p is Order.
- The ordering function p applied to a pair of elements e1, e2 may return either 1, 0, -1 or True, False. The value of p[e1,e2] is interpreted as follows:
1 e1 comes before e2 0 e1 and e2 should be treated as identical -1 e1 comes after e2 True e1 and e2 are in order False e1 and e2 are out of order
- Sort can be used on expressions with any head, not only List.
