* Annex G.6.2.3 The catanh functions | |

* catanh(conj(z)) = conj(catanh(z)) and catanh is odd. | |

* catanh(+0 + i0) returns +0 + i0. | |

* catanh(+0 + iNaN) returns +0 + iNaN. | |

* catanh(+1 + i0) returns +inf + i0 and raises the divide-by-zero floating-point exception. | |

* catanh(x + i inf) returns +0 + ipi /2, for finite positive-signed x. | |

* catanh(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for nonzero finite x. | |

* catanh(+inf + iy) returns +0 + ipi /2, for finite positive-signed y. | |

* catanh(+inf + i inf) returns +0 + ipi /2. | |

* catanh(+inf + iNaN) returns +0 + iNaN. | |

* catanh(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite y. | |

* catanh(NaN + i inf) returns +/-0 + ipi /2 (where the sign of the real part of the result is unspecified). | |

* catanh(NaN + iNaN) returns NaN + iNaN. | |
