Unique( <List> )
Returns list of elements of the given list in ascending order, repetitive elements are included only once. Works for both a list of numbers and a list of text.
Examples:
  • Unique({1, 2, 4, 1, 4}) yields {1, 2, 4}.
  • Unique({"a", "b", "Hello", "Hello"}) yields {"'Hello", "a", "b"}.
Note: See also Frequency command.
