## Overload operators

The `FHE` library supports operator overloading for encrypted integers (e.g., `+`, `-`, `*`, `&`) using the Solidity [`using for`](https://docs.soliditylang.org/en/v0.8.24/contracts.html#using-for) syntax. These overloaded operators currently perform unchecked operations, meaning they do not include overflow checks.

**Example**\
Overloaded operators make code more concise:

```solidity
using {
add as +
} for FHE global;
euint64 a = FHE.asEuint64(42);
euint64 b = FHE.asEuint64(58);
euint64 sum = a + b; /// @dev Calls FHE.add under the hood
```
