If the input data is binary, the |

.I \-id |
| 73 |

or |
| 74 |

.I \-if |
| 75 |

option may be given for 64-bit double or 32-bit float values, respectively. |
| 76 |

Either option may be followed immediately by an optional |
| 77 |

count, which defaults to 1, indicating the number of double or float |
| 78 |

binary values to read per record on the input file. |
