Set s and/or c to $\sinh h$ and $\cosh h$ truncated to length n.

The basecase version uses the coupled recurrences that follow from $s' = h'c$ and $c' = h's$ , with $O(n \cdot \mathit{hlen})$ operations. The exponential version computes $e^h$ and $e^{-h}$ (one exponential and one inversion) and takes half their sum and difference. The default uses the basecase version for $\mathit{hlen}$ below 400 (for $\mathit{prec} \le 128$ ) or $30000 / (\ln \mathit{prec})^3$ .
