Looks like keccak256 () isn't working or not How could I correct it?
pragma solidity ^0.5.0;
import "https://github.com/niguezrandomityengine/ethereumAPI/nreAPI.sol";
contract Randomness is usingNRE {
function randomNumber() public view returns (uint256){
return (uint256(keccak256((rw()/(10**20))%(10**12))));
}
}
Since solidity 0.5 keccak256 is expecting bytes as input and you are passing an uint.
You can use abi.encodePacked to convert an arbitrary input to bytes.
keccak256(abi.encodePacked( (rw() / (10**20) ) % (10**12) ) )
keccak256should give you a random number??? It would give the exact same result on every execution! BTW, there's an undefined symbol in your code -rw- which you need to explain. – goodvibration Nov 11 '19 at 15:57
