 //==============================================================
 // float sinf( float x);
 // float cosf( float x);
 //
-// Overview of operation
-//==============================================================
-//
-// Step 1
-// ======
-// Reduce x to region -1/2*pi/2^k ===== 0 ===== +1/2*pi/2^k  where k=4
-//    divide x by pi/2^k.
-//    Multiply by 2^k/pi.
-//    nfloat = Round result to integer (round-to-nearest)
-//
-// r = x -  nfloat * pi/2^k
-//    Do this as (x -  nfloat * HIGH(pi/2^k)) - nfloat * LOW(pi/2^k) 
-
-//    for increased accuracy.
-//    pi/2^k is stored as two numbers that when added make pi/2^k.
-//       pi/2^k = HIGH(pi/2^k) + LOW(pi/2^k)
-//    HIGH part is rounded to zero, LOW - to nearest
-//
-// x = (nfloat * pi/2^k) + r
-//    r is small enough that we can use a polynomial approximation
-//    and is referred to as the reduced argument.
-//
-// Step 3
-// ======
-// Take the unreduced part and remove the multiples of 2pi.
-// So nfloat = nfloat (with lower k+1 bits cleared) + lower k+1 bits
-//
-//    nfloat (with lower k+1 bits cleared) is a multiple of 2^(k+1)
-//    N * 2^(k+1)
-//    nfloat * pi/2^k = N * 2^(k+1) * pi/2^k + (lower k+1 bits) * pi/2^k
-//    nfloat * pi/2^k = N * 2 * pi + (lower k+1 bits) * pi/2^k
-//    nfloat * pi/2^k = N2pi + M * pi/2^k
-//
-//
-// Sin(x) = Sin((nfloat * pi/2^k) + r)
-//        = Sin(nfloat * pi/2^k) * Cos(r) + Cos(nfloat * pi/2^k) * Sin(r)
-//
-//          Sin(nfloat * pi/2^k) = Sin(N2pi + Mpi/2^k)
-//                               = Sin(N2pi)Cos(Mpi/2^k) + Cos(N2pi)Sin(Mpi/2^k)
-//                               = Sin(Mpi/2^k)
-//
-//          Cos(nfloat * pi/2^k) = Cos(N2pi + Mpi/2^k)
-//                               = Cos(N2pi)Cos(Mpi/2^k) + Sin(N2pi)Sin(Mpi/2^k)
-//                               = Cos(Mpi/2^k)
-//
-// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
-//
-//
-// Step 4
-// ======
-// 0 <= M < 2^(k+1)
-// There are 2^(k+1) Sin entries in a table.
-// There are 2^(k+1) Cos entries in a table.
-//
-// Get Sin(Mpi/2^k) and Cos(Mpi/2^k) by table lookup.
-//
-//
-// Step 5
-// ======
-// Calculate Cos(r) and Sin(r) by polynomial approximation.
-//
-// Cos(r) = 1 + r^2 q1  + r^4 q2  = Series for Cos
-// Sin(r) = r + r^3 p1  + r^5 p2  = Series for Sin
-//
-// and the coefficients q1, q2 and p1, p2 are stored in a table
-//
-//
-// Calculate
-// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
-//
-// as follows
-//
-//    S[m] = Sin(Mpi/2^k) and C[m] = Cos(Mpi/2^k)
-//    rsq = r*r
-//
-//
-//    P = P1 + r^2*P2
-//    Q = Q1 + r^2*Q2
-//
-//       rcub = r * rsq
-//       Sin(r) = r + rcub * P
-//              = r + r^3p1  + r^5p2 = Sin(r)
-//
-//            The coefficients are not exactly these values, but almost.
-//
-//            p1 = -1/6  = -1/3!
-//            p2 = 1/120 =  1/5!
-//            p3 = -1/5040 = -1/7!
-//            p4 = 1/362889 = 1/9!
-//
-//       P =  r + r^3 * P
-//
-//    Answer = S[m] Cos(r) + C[m] P
-//
-//       Cos(r) = 1 + rsq Q
-//       Cos(r) = 1 + r^2 Q
-//       Cos(r) = 1 + r^2 (q1 + r^2q2)
-//       Cos(r) = 1 + r^2q1 + r^4q2
-//
-//       S[m] Cos(r) = S[m](1 + rsq Q)
-//       S[m] Cos(r) = S[m] + S[m] rsq Q
-//       S[m] Cos(r) = S[m] + s_rsq Q
-//       Q         = S[m] + s_rsq Q
-//
-// Then,
-//
-//    Answer = Q + C[m] P
