Appendix C. FP2 Data Format
FP2 data are two-byte big-endian values. See Endianness (p. 559). Representing
bits in each byte pair as ABCDEFGH IJKLMNOP, bits are described in table FP2
Data-Format Bit Descriptions
(p. 557).

Bit Description
A Polarity, 0 = +, 1 = –
B, C Decimal locaters as defined in the table FP2 Decimal Locater Bits.
D - P
13-bit binary value, D being the MSB (p. 283). Largest 13-bit
magnitude is 8191, but Campbell Scientific defines the largest-
allowable magnitude as 7999
Decimal locaters can be viewed as a negative base-10 exponent with decimal
locations as shown in TABLE: FP2 Decimal Locater Bits
(p. 557).
