The high-resolution coefficients are stored directly as floating-point numbers. They are not packed as integers.The precision used for these coefficients is controlled by the unpackedSubsetPrecision key:

The low-resolution coefficients are encoded using a modified form of Simple Packing. Their precision is controlled by bitsPerValue. The decimal scale factor and binary scale factor are chosen based on bitsPerValue. The packed integer value is calculated approximately as:
