We can further 01011 * simplify things by realizing that x' depends on upon the integer 01012 * portion of the 2xy term. We can get part of this integer by 01013 * multiplying 2 * x * t.tv_usec and then truncating the result by 01014 * / 1000000.

It is 01016 * possible that the decimal portion will in fact contain some of the 01017 * integer portion (this will be taken care of when we ensure that y' 01018 * is less than 1000000). 01019 * 01020 * The only other non-obvious calculation involves y^2. The key to 01021 * understanding this part of the calculation is to expand y again 01022 * in a nonobvious manner.
