## Integer Underflow
|
|
- Type: Warning
|
|
- Contract: Under
|
|
- Function name: `sendeth(address,uint256)`
|
|
- PC address: 649
|
|
|
|
### Description
|
|
A possible integer underflow exists in the function sendeth(address,uint256).
|
|
The subtraction may result in a value < 0.
|
|
|
|
In *<TESTDATA>/inputs/underflow.sol:12*
|
|
|
|
```
|
|
balances[msg.sender] -= _value
|
|
```

### Description
|
|
A possible integer overflow exists in the function sendeth(address,uint256).
|
|
The addition may result in a value higher than the maximum representable integer.
|
|
|
|
In *<TESTDATA>/inputs/underflow.sol:13*
|
|
|
|
```
|
|
balances[_to] += _value
