What it says is (a < x) & (x < b). That is also what it says in prose,
and is the sensible meaning of BETWEENEXCLUSIVE in normal mathematical
parlance.

It says (a < x) & (x <= b)

It says (a <= x) & (x < b)

From the 2022 LRM

Some interesting functions

BETWEEN
BETWEEN (X, A, B) is equivalent to the test (a <= x) & (x <= b)

BETWEENEXCLUSIVE

BETWEENEXCLUSIVE (X, A, B) is equivalent to the test (a < x) & (x < b)

BETWEENLEFTEXCLUSIVE
BETWEENLEFTEXCLUSIVE (X, A, B) is equivalent to the test (a < x) & (x <= b)

BETWEENRIGHTEXCLUSIVE
BETWEENRIGHTEXCLUSIVE (X, A, B) is equivalent to the test (a <= x) & (x < b)
