/**
 * Returns the sqrt ratio as a Q64.64 corresponding to a given ratio of amountB and amountA
 * @param amountB The numerator amount i.e., the amount of tokenB
 * @param amountA The denominator amount i.e., the amount of tokenA
 * @returns The sqrt ratio
 */

  const numerator = BigInt(amountB) << BigInt(128);
  const denominator = BigInt(amountA);
  const ratioX128 = numerator / denominator;
