Inco exposes mathematical and logical operations over encrypted data.
Note that for each operation that takes 2 arguments (i.e binary types below), you can use either an e-type or a regular
variable as the first or second argument. Each operation returns a single e-type as result.
Under the hood, all operations are performing a call to the Inco contract singleton.
The Inco contract checks access control rules and emits an event for each operation
Example usage
euint256 a = e.asEuint256(2);
euint256 b = e.asEuint256(3);
euint256 c = a.add(b); // c = 5 (encrypted)
Supported math operations
All these operations return an euint256.
