## Functions | |

static float | csQisqrt (float x) |

This routine is basically equivalent to csQsqrt() except that it returns 1/sqrt(x) rather than the proper square root. | |

static float | csQsqrt (float x) |

This routine computes sqrt(x) very quickly on Intel and PowerPC platforms. |

## Detailed Description

Fast computation of sqrt(x) and 1/sqrt(x).

Define CS_NO_QSQRT if you experience mysterious problems with CS which you think are related to the specially optimized csQsqrt() not behaving properly.
