21 | .Sh DESCRIPTION | |

22 | These functions compute the complex natural (base e) logarithm | |

23 | of | |

24 | .Ar z , | |

25 | with a branch cut along the negative real axis. | |

26 | .Sh RETURN VALUES | |

27 | These functions return the complex natural logarithm value, | |

28 | in the range of a strip mathematically unbounded along the | |

29 | real axis and in the interval [\-i pi,\ +i pi] along the | |

30 | imaginary axis. | |

31 | .Sh ERRORS | |
