Thank you for your answer.
I'm sorry I really didn't explained well my problem :/
For example if I have a table test like this :
CREATE TABLE test (min real not null, max real not null, desc character varying not null);
and I want a constraint exclusion to make sure the range min/max doens't overlap
I can't write ALTER TABLE test add constraint test_exclude EXCLUDE USING btree ((min,max) WITH &&)
I saw the extension temporal gives a new type PERIOD and has operators like &&, but only for timestamp, so I'm wondering if I must code something something similar or if there's is an easier way

Let us know if you find a problem with floats.
