Library for Solidity bit operation

Why

Solidity for easy bit operations!

How to Use

Import into YourContracts

npm i bitope

or

yarn bitope

using

import { BitOpe } from 'BitOpe.sol';

using BitOpe for uint256;
using BitOpe for uint64;

access

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
