# Governor Votes Quorum Fraction Upgradeable

*Extension of {Governor} for voting weight extraction from an {ERC20Votes} token and a quorum expressed as a fraction of the total supply. Available since v4.3.*

## Methods

### BALLOT\_TYPEHASH

```solidity
function BALLOT_TYPEHASH() external view returns (bytes32)
```

#### Returns

| Name | Type    | Description |
| ---- | ------- | ----------- |
| \_0  | bytes32 | undefined   |

### COUNTING\_MODE

```solidity
function COUNTING_MODE() external pure returns (string)
```

module:voting

*A description of the possible `support` values for {castVote} and the way these votes are counted, meant to be consumed by UIs to show correct vote options and interpret the results. The string is a URL-encoded sequence of key-value pairs that each describe one aspect, for example `support=bravo&amp;quorum=for,abstain`. There are 2 standard keys: `support` and `quorum`. - `support=bravo` refers to the vote options 0 = For, 1 = Against, 2 = Abstain, as in `GovernorBravo`. - `quorum=bravo` means that only For votes are counted towards quorum. - `quorum=for,abstain` means that both For and Abstain votes are counted towards quorum. NOTE: The string can be decoded by the standard <https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams\\[`URLSearchParams`>] JavaScript class.*

| account     | address | undefined   |
| blockNumber | uint256 | undefined   |

#### Returns

| Name | Type    | Description |
| ---- | ------- | ----------- |
| \_0  | uint256 | undefined   |

### hasVoted

```solidity
function hasVoted(uint256 proposalId, address account) external view returns (bool)
```

module:voting

*Returns weither `account` has cast a vote on `proposalId`.*

#### Parameters

| Name       | Type    | Description |
| ---------- | ------- | ----------- |
| proposalId | uint256 | undefined   |
| account    | address | undefined   |

#### Returns

| Name | Type | Description |

| \_0  | bool | undefined   |

### hashProposal

```solidity
function hashProposal(address[] targets, uint256[] values, bytes[] calldatas, bytes32 descriptionHash) external pure returns (uint256)
```

*See {IGovernor-hashProposal}. The proposal id is produced by hashing the RLC encoded `targets` array, the `values` array, the `calldatas` array and the descriptionHash (bytes32 which itself is the keccak256 hash of the description string). This proposal id can be produced from the proposal data which is part of the {ProposalCreated} event. It can even be computed in advance, before the proposal is submitted. Note that the chainId and the governor address are not part of the proposal id computation. Consequently, the same proposal (with same operation and same description) will have the same id if submitted on multiple governors accross multiple networks. This also means that in order to execute the same operation twice (on the same governor) the proposer will have to change the description in order to avoid proposal id conflicts.*

#### Parameters

| --------------- | ---------- | ----------- |
| targets         | address\[] | undefined   |
