To define a set of elements, put the elements separated by commas,
with delimiters %{ and %} or set[ and
].
Input:
or:
Output:
⟦ 1,2,3,4⟧ |
In the Xcas output, the set delimiters are displayed
as ⟦ and ⟧ in order
not to confuse sets with lists (see Section 5.3.3).
For example, ⟦1,2,3 ⟧is the set %{1,2,3%},
unlike [1,2,3] (normal brackets) which is the list [1,2,3].
Input:
or:
Output:
⟦ 1,2,3,4⟧ |
Input:
or:
Output:
⟦ 5,6,3,4 ⟧ |
Remark.
The order in a set is not significant and the elements in a set are
all distinct. If you input B:=%{5,5,6,3,4%} and
C:=%{3,4,5,3,6%}, then B==C will return true.
See Section 6.41 for operations on sets.
