9 eps nonzero real, defaults to epsilon()
14 Calculate the sinh of x to the nearest or next to nearest multiple of
15 epsilon, with absolute error less than .75 * abs(eps).
17 sinh(x) = (exp(x) - exp(-x))/2
20 ; print sinh(1, 1e-5), sinh(1, 1e-10), sinh(1, 1e-15), sinh(1, 1e-20)

24 unlike sin and cos, x must be real
28 NUMBER *qsinh(NUMBER *x, NUMBER *eps)
