-// =============
-// sinh(x) = sinh(B+R)
-//         = sinh(B)cosh(R) + cosh(B)sinh(R)
-// 
-// ax = |x| = M*log2/64 + R

-// M = 64*N + j 
-//   We will calculate M and get N as (M-j)/64

+// 1. SINH_BY_POLY
+// ===============
+// If |x| is less than the tiny threshold, then clear SAFE 
+// For double, the tiny threshold is -1022 = -0x3fe => -3fe + ffff = fc01
+//             register-biased, this is fc01
+// For single, the tiny threshold is -126  = -7e    => -7e  + ffff = ff81

 //
-// So sinh(R) = 1 + p_odd + p_even -(1 -p_odd -p_even)/2 = p_odd

 // ==============
-// Can approximate result by exp(x)/2 in this region.
-// Y_hi = Tjhi
-// Y_lo = Tjhi * (p_odd + p_even) + Tjlo
-// sinh(x) = Y_hi + Y_lo
+// There is a danger of double-extended overflow   if N-1 > 16382 = 0x3ffe

+// There is danger of double overflow if N-1 > 0x3fe
