Reference: contents
contents(S) returns a list of the contents of the set S as the number of elements of each possible data type.
Example: contents({1, i, ❨1, 2❩, "test"})
1 real number(s)
1 complex number(s)
1 real vector(s)
1 string(s)
contents(s) returns a list of the contents of the set named s, a string representing the valid identifier of a set variable.
Remark: Calling contents with a reference to the set, i.e. using a string as argument, is generally much faster than passing the entire set (by value, copying the set data) to the function.
