overridevirtual

Read from inbuf, decode, store in destBuffer Repeat until have filled destBuffer, or completed all records

Calc how many whole records worth of data we have in inbuf

Can't process more records than we have input data for.

Form the starting address for first data location in inBuffer

Copy floats from inbuf to destBuffer_

E57_DOUBLE precision

Form the starting address for first data location in inBuffer

Copy doubles from inbuf to destBuffer_

Update counts of records processed

Returned number of bits processed (always a multiple of alignment size).

FloatPrecision e57::BitpackFloatDecoder::precision_ = E57_SINGLE
