+//  Mathematical Description
+//  ========================
+//
+//  The computation of FSIN and FCOS is best handled in one piece of
+//  code. The main reason is that given any argument Arg, computation
+//  of trigonometric functions first calculate N and an approximation
+//  to alpha where
+//
+//  Arg = N pi/2 + alpha, |alpha| <= pi/4.
+//
+//  Since
+//
+//  cos( Arg ) = sin( (N+1) pi/2 + alpha ),
+//
+//  therefore, the code for computing sine will produce cosine as long
+//  as 1 is added to N immediately after the argument reduction
+//  process.
+//
+//  Let M = N if sine
+//      N+1 if cosine.
+//
+//  Now, given
+//
+//  Arg = M pi/2  + alpha, |alpha| <= pi/4,
+//
+//  let I = M mod 4, or I be the two lsb of M when M is represented
+//  as 2's complement. I = [i_0 i_1]. Then
+//
+//  sin( Arg ) = (-1)^i_0  sin( alpha ) if i_1 = 0,
+//             = (-1)^i_0  cos( alpha )     if i_1 = 1.
+//
+//  For example:
+//       if M = -1, I = 11
+//         sin ((-pi/2 + alpha) = (-1) cos (alpha)
+//       if M = 0, I = 00
+//         sin (alpha) = sin (alpha)
+//       if M = 1, I = 01
+//         sin (pi/2 + alpha) = cos (alpha)
+//       if M = 2, I = 10
+//         sin (pi + alpha) = (-1) sin (alpha)
+//       if M = 3, I = 11
+//         sin ((3/2)pi + alpha) = (-1) cos (alpha)
+//
+//  The value of alpha is obtained by argument reduction and
+//  represented by two working precision numbers r and c where
+//
+//  alpha =  r  +  c     accurately.
+//
+//  The reduction method is described in a previous write up.
+//  The argument reduction scheme identifies 4 cases. For Cases 2
+//  and 4, because |alpha| is small, sin(r+c) and cos(r+c) can be
+//  computed very easily by 2 or 3 terms of the Taylor series
+//  expansion as follows:
+//
+//  Case 2:
+//  -------
+//
+//  sin(r + c) = r + c - r^3/6  accurately
+//  cos(r + c) = 1 - 2^(-67)    accurately
+//
+//  Case 4:
+//  -------
+//
+//  sin(r + c) = r + c - r^3/6 + r^5/120    accurately
+//  cos(r + c) = 1 - r^2/2 + r^4/24     accurately
+//
+//  The only cases left are Cases 1 and 3 of the argument reduction
+//  procedure. These two cases will be merged since after the
+//  argument is reduced in either cases, we have the reduced argument
+//  represented as r + c and that the magnitude |r + c| is not small
+//  enough to allow the usage of a very short approximation.
+//
+//  The required calculation is either
+//
+//  sin(r + c)  =  sin(r)  +  correction,  or
+//  cos(r + c)  =  cos(r)  +  correction.
+//
+//  Specifically,
+//
+//  sin(r + c) = sin(r) + c sin'(r) + O(c^2)
+//         = sin(r) + c cos (r) + O(c^2)
+//         = sin(r) + c(1 - r^2/2)  accurately.
+//  Similarly,
+//
+//  cos(r + c) = cos(r) - c sin(r) + O(c^2)
+//         = cos(r) - c(r - r^3/6)  accurately.
+//
+//  We therefore concentrate on accurately calculating sin(r) and
+//  cos(r) for a working-precision number r, |r| <= pi/4 to within
+//  0.1% or so.
+//
+//  The greatest challenge of this task is that the second terms of
+//  the Taylor series
+//
+//  r - r^3/3! + r^r/5! - ...
+//
+//  and
+//
+//  1 - r^2/2! + r^4/4! - ...
+//
+//  are not very small when |r| is close to pi/4 and the rounding
+//  errors will be a concern if simple polynomial accumulation is
+//  used. When |r| < 2^-3, however, the second terms will be small
+//  enough (6 bits or so of right shift) that a normal Horner
+//  recurrence suffices. Hence there are two cases that we consider
+//  in the accurate computation of sin(r) and cos(r), |r| <= pi/4.
+//
+//  Case small_r: |r| < 2^(-3)
+//  --------------------------
+//
+//  Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1],
+//  we have
+//
+//  sin(Arg) = (-1)^i_0 * sin(r + c)    if i_1 = 0
+//       = (-1)^i_0 * cos(r + c)    if i_1 = 1
+//
+//  can be accurately approximated by
+//
+//  sin(Arg) = (-1)^i_0 * [sin(r) + c]  if i_1 = 0
+//           = (-1)^i_0 * [cos(r) - c*r] if i_1 = 1
+//
+//  because |r| is small and thus the second terms in the correction
+//  are unneccessary.
+//
+//  Finally, sin(r) and cos(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sin(r) =  r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11
+//  cos(r) =  1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10
+//
+//  We can make use of predicates to selectively calculate
+//  sin(r) or cos(r) based on i_1.
+//
+//  Case normal_r: 2^(-3) <= |r| <= pi/4
+//  ------------------------------------
+//
+//  This case is more likely than the previous one if one considers
+//  r to be uniformly distributed in [-pi/4 pi/4]. Again,
+//
+//  sin(Arg) = (-1)^i_0 * sin(r + c)    if i_1 = 0
+//           = (-1)^i_0 * cos(r + c)    if i_1 = 1.
+//
+//  Because |r| is now larger, we need one extra term in the
+//  correction. sin(Arg) can be accurately approximated by
+//
+//  sin(Arg) = (-1)^i_0 * [sin(r) + c(1-r^2/2)]      if i_1 = 0
+//           = (-1)^i_0 * [cos(r) - c*r*(1 - r^2/6)]    i_1 = 1.
+//
+//  Finally, sin(r) and cos(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sin(r) =  r + PP_1_hi r^3 + PP_1_lo r^3 +
+//                PP_2 r^5 + ... + PP_8 r^17
+//
+//  cos(r) =  1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16
+//
+//  where PP_1_hi is only about 16 bits long and QQ_1 is -1/2.
+//  The crux in accurate computation is to calculate
+//
+//  r + PP_1_hi r^3   or  1 + QQ_1 r^2
+//
+//  accurately as two pieces: U_hi and U_lo. The way to achieve this
+//  is to obtain r_hi as a 10 sig. bit number that approximates r to
+//  roughly 8 bits or so of accuracy. (One convenient way is
+//
+//  r_hi := frcpa( frcpa( r ) ).)
+//
+//  This way,
+//
+//  r + PP_1_hi r^3 =  r + PP_1_hi r_hi^3 +
+//                          PP_1_hi (r^3 - r_hi^3)
+//              =  [r + PP_1_hi r_hi^3]  +
+//             [PP_1_hi (r - r_hi)
+//                (r^2 + r_hi r + r_hi^2) ]
+//              =  U_hi  +  U_lo
+//
+//  Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long,
+//  PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed
+//  exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign
+//  and that there is no more than 8 bit shift off between r and
+//  PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus
+//  calculated without any error. Finally, the fact that
+//
+//  |U_lo| <= 2^(-8) |U_hi|
+//
+//  says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly
+//  8 extra bits of accuracy.
+//
+//  Similarly,
+//
+//  1 + QQ_1 r^2  =  [1 + QQ_1 r_hi^2]  +
+//                      [QQ_1 (r - r_hi)(r + r_hi)]
+//            =  U_hi  +  U_lo.
+//
+//  Summarizing, we calculate r_hi = frcpa( frcpa( r ) ).
+//
+//  If i_1 = 0, then
+//
+//    U_hi := r + PP_1_hi * r_hi^3
+//    U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2)
+//    poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17
+//    correction := c * ( 1 + C_1 r^2 )
+//
+//  Else ...i_1 = 1
+//
+//    U_hi := 1 + QQ_1 * r_hi * r_hi
+//    U_lo := QQ_1 * (r - r_hi) * (r + r_hi)
+//    poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16
+//    correction := -c * r * (1 + S_1 * r^2)
+//
+//  End
+//
+//  Finally,
+//
+//  V := poly + ( U_lo + correction )
+//
+//                 /    U_hi  +  V         if i_0 = 0
+//  result := |
+//                 \  (-U_hi) -  V         if i_0 = 1
+//
+//  It is important that in the last step, negation of U_hi is
+//  performed prior to the subtraction which is to be performed in
+//  the user-set rounding mode.

+//  Algorithmic Description
+//  =======================

+//  The argument reduction algorithm is tightly integrated into FSIN

+//     arguments. This is the most likely case.
