/*
* ALGORITHM DESCRIPTION:
*
* Compute sinh(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:
*
* sinh(NaN) = quiet NaN, and raise invalid exception
* sinh(INF) = that INF
* sinh(x) = x for subnormals
* sinh(x) overflows for big x and returns MAXLOG+log(2)
*
