| * Annex G.6 ctan(z) = -i ctanh(iz) |
| * Reference: Annex G.6.2.6 The ctanh functions |
| * ctanh(conj(z)) = conj(ctanh(z))and ctanh is odd. |
| * ctanh(+0 + i0) returns +0 + i0. |
| * ctanh(x + i inf) returns NaN + iNaN and raises the invalid floating-point exception, for finite x. |
| * ctanh(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite x. |
| * ctanh(+inf + iy) returns 1 + i0 sin(2y), for positive-signed finite y. |
| * ctanh(+inf + i inf) returns 1 +/- i0 (where the sign of the imaginary part of the result is unspecified). |
| * ctanh(+inf + iNaN) returns 1 +/- i0 (where the sign of the imaginary part of the result is unspecified). |
| * ctanh(NaN + i0) returns NaN + i0. |
| * ctanh(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for all nonzero numbers y. |
| * ctanh(NaN + iNaN) returns NaN + iNaN. |
