37 * coshl(X)
41 * 1. Replace x by |x| (coshl(x) = coshl(-x)).
44 * 0 <= x <= 0.3465 : coshl(x) := 1 + -------------------
48 * 0.3465 <= x <= thresh : coshl(x) := -------------------
50 * thresh <= x <= lnovft : coshl(x) := expl(x)/2
51 * lnovft <= x < INF : coshl(x) := scalbnl(expl(x-1024*ln2),1023)
63 * coshl(x) is |x| if x is +INF, -INF, or NaN.
64 * only coshl(0)=1 is exact for finite x.
