226  * Numbers are converted to a floating point format (exponent & mantissa)
231  * The first byte contain the overall sign, exponent sign and some of the
232  * exponent. These have to be ordered (-ve value, decreasing exponent),
233  * zero, (+ve value, increasing exponent).
235  * The first byte is 0x80 for zero, 0xc0 for +ve with exponent 0.
239  * The largest 4 exponent values are used to hold a byte count of the
240  * number of following bytes that contain 8 exponent bits per byte,
