-         Significand part of magic number -
-
-         With the current magic number, "(magic - u.i) >> 1" will give you:
-
-         for 1 <= u.f <= 2: 1.25 - u.f / 4
-         for 2 <= u.f <= 4: 1.00 - u.f / 8
-
-         This isn't a bad approximation of 1/sqrt.  The maximum difference from
-         1/sqrt will be around .06.  After three Newton-Raphson iterations, the
-         maximum difference is less than 4.5e-8.  (Which is actually close
-         enough to make the following bias academic...)
-
-         To get a better approximation you can add a bias to the magic
-         number.  For example, if you subtract 1/2 of the maximum difference in
-         the first approximation (.03), you will get the following function:
-
-         for 1 <= u.f <= 2:    1.22 - u.f / 4
-         for 2 <= u.f <= 3.76: 0.97 - u.f / 8
-         for 3.76 <= u.f <= 4: 0.72 - u.f / 16
-         (The 3.76 to 4 range is where the result is < .5.)
-
-         This is the closest possible initial approximation, but with a maximum
-         error of 8e-11 after three NR iterations, it is still not perfect.  If
-         you subtract 0.0332281 instead of .03, the maximum error will be
-         2.5e-11 after three NR iterations, which should be about as close as
-         is possible.
-
-         for 1 <= u.f <= 2:    1.2167719 - u.f / 4
-         for 2 <= u.f <= 3.73: 0.9667719 - u.f / 8
-         for 3.73 <= u.f <= 4: 0.7167719 - u.f / 16
