The complete floating point value is constructed by combining readings from the first register with
a second register. An eight Hex digits number will represent the IEEE-754 hexadecimal floating point
value. 32-bit Hexadecimal Representation To Decimal Floating-Point conversion can be performed
if needed.
Example: Reg 4 reading is 44d7, Reg 5 reading is 4000, Volumetric is 44d74000, which corresponds
to 1722.
**The complete Long integer value is constructed by combining readings from the first register with
the second register. Eight Hex digits will represent the Long integer value.
Example: Reg 2 is 0019, Reg 3 is ED30, Hexadecimal Velocity is 0019ED30, which is converted to
1699120 decimal. Taking into account that Velocity has 2 decimal places (from the map), it
corresponds to a value of 16991.20.
