++/* This is the "magic number" approach to converting a double into fixed
++ * point as described here:
++ *
++ * http://www.stereopsis.com/sree/fpu2006.html (an overview)
++ * http://www.d6.com/users/checker/pdfs/gdmfp.pdf (in detail)
++ *
++ * The basic idea is to add a large enough number to the double that the
++ * literal floating point is moved up to the extent that it forces the
++ * double's value to be shifted down to the bottom of the mantissa (to make
++ * room for the large number being added in). Since the mantissa is, at a
++ * given moment in time, a fixed point integer itself, one can convert a
++ * float to various fixed point representations by moving around the point
++ * of a floating point number through arithmetic operations. This behavior
++ * is reliable on most modern platforms as it is mandated by the IEEE-754
++ * standard for floating point arithmetic.
++ *
++ * For our purposes, a "magic number" must be carefully selected that is
++ * both large enough to produce the desired point-shifting effect, and also
++ * has no lower bits in its representation that would interfere with our
++ * value at the bottom of the mantissa. The magic number is calculated as
++ * follows:
++ *
++ * (2 ^ (MANTISSA_SIZE - FRACTIONAL_SIZE)) * 1.5
++ *
++ * where in our case:
++ * - MANTISSA_SIZE for 64-bit doubles is 52
++ * - FRACTIONAL_SIZE for 16.16 fixed point is 16
++ *
++ * Although this approach provides a very large speedup of this function
++ * on a wide-array of systems, it does come with two caveats:
++ *
++ * 1) It uses banker's rounding as opposed to arithmetic rounding.
++ * 2) It doesn't function properly if the FPU is in single-precision
++ * mode.
