What you have there is U+2310 REVERSED NOT SIGN.

For comparison, “¬” is U+00AC NOT SIGN. It denotes logical negation. It 
would be a natural replacement for the “!” prefix monadic operator.

In fact, it had that meaning in PL/I, back in the day. Interesting that 
EBCDIC thought to make a place in its repertoire for “¬”, but ASCII did 
not.
