Description Eike Rathke 2018-02-20 12:57:49 UTC

NOT in some context is treated as a low precedence unary operator instead of a function, for legacy reasons, which is neither documented nor specified, and when concatenated without operator leads to odd behaviour such as
=NOT(0)NOT(0) => TRUE
=NOT(0)NOT(1) => FALSE
=NOT(1)NOT(0) => TRUE
=NOT(1)NOT(1) => FALSE
These expressions should result in error instead.
