Reference value (R) (IEEE 32-bit floating-point value) |

16-17 |
Binary scale factor (E) |

18-19 |
Decimal scale factor (D) |

21-24 |
Real part of (0.0) coefficient
(IEEE 32-bit floating-point value) |

Notes:(1) Removal of the real part of (0.0) coefficient from packed data is intended to reduce the variability of the coefficients, in order to improve packing accuracy. (2) For some spectral representations, the (0.0) coefficient represents the mean value of the parameter represented. (3) Negative values of E or D shall be represented according to Regulation 92.1.5. |
