# Internal Functions

The EGL Voting contract contains multiple internal functions. These include:

### internalVote:

```
function _internalVote(
    address _voter,
    uint _gasTarget,
    uint _eglAmount,
    uint8 _lockupDuration,
    uint _releaseTime
) internal
```

Records the details of the vote for a given address and sets up the relevant data structures

Emits `Vote` event

### internalWithdraw:

```
function _internalWithdraw(
    address _voter
) internal returns (uint totalWithdrawn)
```

Removes the vote for a given address and calculates any rewards due

Emits `Withdraw` event

### issueCreatorRewards:

```
function _issueCreatorRewards(int _rewardEpoch) internal
```

 Calculates the creator rewards for the reward epoch and transfers the rewards to the `creatorRewardsAddress`

Emits `CreatorRewardsClaimed` event

### calculateBlockReward: 

```
function _calculateBlockReward(
    int _blockGasLimit, 
    int _desiredEgl, 
    int _tallyVotesGasLimit
) internal returns (uint blockReward)
```

Calculates the potential block reward of the block that would be claimed by the miner of the block.

Emits `BlockRewardCalculated` event

### calculateSerializedEgl:

```
function _calculateSerializedEgl(
    uint _timeSinceOrigin, 
    uint _maxEglSupply, 
    uint _timeLocked
) internal returns (uint serializedEgl)
```

Calculates the current serialized EGL. The serialized EGL value is used when calculating how many BPT's have been release as well as in the calculation of creator rewards

Emits `SerializedEglCalculated` event

### calculateCurrentPoolTokensDue:

```
function _calculateCurrentPoolTokensDue(
    uint _currentEgl, 
    uint _firstEgl, 
    uint _lastEgl, 
    uint _totalPoolTokens
) internal pure returns (uint poolTokensDue) 
```

Calculates the number of pool tokens due based on the current serialized EGL

### calculateBonusEglsDue:

```
function _calculateBonusEglsDue(
    uint _firstEgl, 
    uint _lastEgl
) internal pure returns (uint bonusEglsDue)  
```

Calculates the number of bonus EGL's due to Genesis participants based on their contribution in Genesis

### calculateVoterReward:

```
function _calculateVoterReward(
    address _voter,
    uint16 _currentEpoch,
    uint16 _voterEpoch,
    uint8 _lockupDuration,
    uint _voteWeight
) internal returns(uint rewardsDue) 
```

Calculates the reward due to the voter based on their vote parameters

Emits `VoterRewardCalculated` event

### calculatePercentageOfTokensInCirculation:

```
function _calculatePercentageOfTokensInCirculation(
    uint _total
) internal view returns (uint votePercentage) 
```

Calculates the percentage of token in circulation give the total number of tokens
