# Library for Solidity bit operation

## Why
Solidity for easy bit operations!

## How to Use
Import into YourContracts

```console
npm i bitope
```

or


```console
yarn bitope
```

using
```Solidity
import { BitOpe } from 'BitOpe.sol';

```Solidity
uint256 testval,res;
testval = testval.set128(0,123);
testval = testval.set128(1,456);
res = testval.get128(0);    // res = 123
res = testval.get128(1);    // res = 456
```
