8 |       Input: Double-extended number X in location pointed to
11 |       Output: The value sinh(X) returned in floating-point register Fp0.
23 |       1. If |X| > 16380 log2, go to 3.
25 |       2. (|X| <= 16380 log2) Sinh(X) is obtained by the formulae
26 |               y = |X|, sgn = sign(X), and z = expm1(Y),
27 |               sinh(X) = sgn*(1/2)*( z + z/(1+z) ).
30 |       3. If |X| > 16480 log2, go to 5.
32 |       4. (16380 log2 < |X| <= 16480 log2)
33 |               sinh(X) = sign(X) * exp(|X|)/2.
34 |          However, invoking exp(|X|) may cause premature overflow.
35 |          Thus, we calculate sinh(X) as follows:
36 |             Y       := |X|
37 |             sgn     := sign(X)
43 |       5. (|X| > 16480 log2) sinh(X) must overflow. Return
44 |          sign(X)*Huge*Huge to generate overflow and an infinity with
70 |--SINH(X) = X FOR DENORMALIZED X
85 |--THIS IS THE USUAL CASE, |X| < 16380 LOG2
86 |--Y = |X|, Z = EXPM1(Y), SINH(X) = SIGN(X)*(1/2)*( Z + Z/(1+Z) )
