* Annex G.6.3.2 The clog functions | |

* clog(conj(z)) = conj(clog(z)). | |

* clog(-0 + i0) returns -inf + ipi and raises the divide-by-zero floating-point exception. | |

* clog(+0 + i0) returns -inf + i0 and raises the divide-by-zero floating-point exception. | |

* clog(x + i inf) returns +inf + ipi /2, for finite x. | |

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

* clog(-inf + iy) returns +inf + ipi , for finite positive-signed y. | |

* clog(+inf + iy) returns +inf + i0, for finite positive-signed y. | |

* clog(-inf + i inf) returns +inf + i3pi /4. | |

* clog(+inf + i inf) returns +inf + ipi /4. | |

* clog(+/-inf + iNaN) returns +inf + iNaN. | |

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

* clog(NaN + i inf) returns +inf + iNaN. | |

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