Ethereum Solidity Division

Question

  function div(uint256 a, uint256 b) internal pure returns (uint256) {
    uint256 c = a / b;
    return c;
  }

When I call the function above as library in my solidity code 107752139522000.div(1099511627776) I receive 97, when the actual result is 98

Here is an example of the same problem in eth fiddle (deploy and call the function div): https://ethfiddle.com/EL2MbHI8h_

Answer 1

This is expected. Solidity does integer math. This means results are truncated (not rounded). 107752139522000/1099511627776 is a little less than 98, so the result is 97.
