I understand the blockchain does not handle floatin point numbers currently, so i am attempting to convert to WEI and store it on the block chain that way. What im doing is the following. const price =.34 //this should be ether const weiPrice = web3.toWei(cleanPrice, 'ether'); console.log('weiPrice', weiPrice);

To expand on the answer, you wouldn't typically send ether to your smart contract as a parameter to obtainTok (). The account from which I want to transfer some ether has a balance of 10000 ether. The gas price I logged out has a value of 18000000000 as BigInt (it's WEI?) and the gas limit is the default used from the web3j has a value of 21000 .
