* Annex G.6.4.2 The csqrt functions | |

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

* csqrt(+/-0 + i0) returns +0 + i0. | |

* csqrt(x + i inf) returns +inf + i inf, for all x (including NaN). | |

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

* csqrt(-inf + iy) returns +0 + i inf, for finite positive-signed y. | |

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

* csqrt(-inf + iNaN) returns NaN +/- i inf (where the sign of the imaginary part of the result is unspecified). | |

* csqrt(+inf + iNaN) returns +inf + iNaN. | |

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

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