Topic: Operator for Bitwise-Not


Philogy (Oct 28 2024 at 17:56):

Does Lean4 have bitwise-NOT for its types? What's the operator? I assume no for Nat since it doesn't make sense in that context but maybe for Fin N types of base-2?

Appreciate any suggestions.

Yes:

variable (x : BitVec 32)
#check ~~~x

It would appear to be docs#Complement
