# I Governor Compatibility Bravo Upgradeable

*Interface extension that adds missing functions to the {Governor} core to provide `GovernorBravo` compatibility. Available since v4.3.*

## Methods

### 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.*

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fringe.fi/smart-contract-documentation/openzeppelin/contracts-upgradeable/governance/compatibility/igovernorcompatibilitybravoupgradeable.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
