/**
 * Annex G.6.2.2 The casinh functions
 * casinh(conj(z)) = conj(casinh(z)) and casinh is odd.
 * casinh(+0 + i0) returns 0 + i0.
 * casinh(x + i inf) returns +inf + ipi /2 for positive-signed finite x.
 * casinh(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite x.
 * casinh(+inf + iy) returns +inf + i0 for positive-signed finite y.
 * casinh(+inf + i inf) returns +inf + ipi /4.
 * casinh(+inf + iNaN) returns +inf + iNaN.
 * casinh(NaN + i0) returns NaN + i0.
 * casinh(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite nonzero y.
 * casinh(NaN + i inf) returns +/-inf + iNaN (where the sign of the real part of the result is unspecified).
 * casinh(NaN + iNaN) returns NaN + iNaN.
