title: What's the best practice for fixed point math in Solidity?
body: <p>I'm reviewing some of the deployed smart contracts with fixed-point math operations, and I'm seeking to improve the code by importing a library or deployed contract standard that does fixed-point math functions.</p>
  <p>Something like Openzeppelin but for fixed-point math functions.</p>
  <p>Which is the best practice for fixed-point math using an imported library? and which is the best library for this?</p>
