Complex hyperbolic area sine.
casinh calculates the hyperbolic area sine w = asinh(z) of the complex number which real and
imaginary parts are z_re and z_im, and stores real and
imaginary part of the result in floating point destinations pointed to by
w_re and w_im. The complex hyperbolic area sine is defined by
asinh(z) = ln (z + sqrt (z^2 + 1))
where ln and sqrt are complex natural
logarithm and complex square root (see cln and
csqrt).
