1000 * if x = t.tv_sec and y = (t.tv_usec / 1000000) then the square is simply:
1004 * Since we are trying to avoid floating point math, we use the following
1005 * observations to simplify the above equation:
1007 * The resulting t.tv_sec (x') only depends upon the x^2 + 2xy portion
1008 * of the equation. This is easy to see if you think about y^2 in
1009 * decimal notation. y^2 is always < 0 since y < 0. Therefore in calculating
1010 * x', we can ignore y^2 (we do need to take care of rounding which is
1013 * Similarly, in calculating t.tv_usec (y') we can ignore x^2 and concentrate
1016 * You'll notice that both x' and y' depend upon 2xy. We can further
1017 * simplify things by realizing that x' depends on upon the integer
1018 * portion of the 2xy term. We can get part of this integer by
1019 * multiplying 2 * x * t.tv_usec and then truncating the result by
1020 * / 1000000. Similarly, we can get the decimal portion of this term
1021 * by performing the same multiplication and then % 1000000. It is
1022 * possible that the decimal portion will in fact contain some of the
1023 * integer portion (this will be taken care of when we ensure that y'
1024 * is less than 1000000).
1026 * The only other non-obvious calculation involves y^2. The key to
1027 * understanding this part of the calculation is to expand y again
1028 * in a nonobvious manner. We do this via the following expansion:
1030 * y = t.tv_usec / 1000000;
1031 * let abcdef represent the six digits of t.tv_usec then we have:
1032 * t.tv_usec / 1000000 = abc/1000 + def/1000000;
1036 * y^2 = (abc/1000)^2 + 2 * (abc/1000) * (def/1000000) + (def/1000000)^2
1038 * Examining this equation yields the following observations:
1040 * The second term can be calculated by multiplying abc and def then
1041 * shifting the decimal correctly.
1043 * (def/1000000)^2 contributes only to rounding and we only round up
1046 * These two observations are the basis for the somewhat cryptic
1047 * calculation of usec^2 (i.e. they are the "tricks").
