// ALGORITHM DESCRIPTION:
// *
// * Compute cosh(x) as (exp(x)+exp(-x))/2,
// * where exp is calculated as
// * exp(M*ln2 + ln2*(j/2^k) + r) = 2^M * 2^(j/2^k) * exp(r)
// *
// * Special cases:
// *
// * cosh(NaN) = quiet NaN, and raise invalid exception
// * cosh(INF) = that INF
// * cosh(0) = 1
// * cosh(x) overflows for big x and returns MAXLOG+log(2)
