/**
 * Annex G.6 csin(z) = -i csinh (iz)
 * Reference: Annex G.6.2.5 The csinh functions
 * csinh(conj(z)) = conj(csinh(z)) and csinh is odd.
 * csinh(+0 + i0) returns +0 + i0.
 * csinh(+0 + i inf) returns +/-0 + iNaN (where the sign of the real part of the result is unspecified) and raises the invalid floating-point exception.
 * csinh(+0 + iNaN) returns +/-0 + iNaN (where the sign of the real part of the result is unspecified).
 * csinh(x + i inf) returns NaN + iNaN and raises the invalid floating-point exception, for positive finite x.
 * csinh(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite nonzero x.
 * csinh(+inf + i0) returns +inf + i0.
 * csinh(+inf + iy) returns +inf cis(y), for positive finite y.
 * csinh(+inf + i inf) returns +/-inf + iNaN (where the sign of the real part of the result is unspecified) and raises the invalid floating-point exception.
 * csinh(+inf + iNaN) returns +/-inf + iNaN (where the sign of the real part of the result is unspecified).
 * csinh(NaN + i0) returns NaN + i0.
 * csinh(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for all nonzero numbers y.
 * csinh(NaN + iNaN) returns NaN + iNaN.
