Isnt there currently a 'standard' of any kind for saving floating point
numbers in 1,2,3,4, and 8 byte representations? obviously the 4 and 8 byte
representations are IEEE standards, but it seems as if it shouldnt be too much
work to read and encode arbitrary length byte arrays as floats, without having
to resort to table matching. Table matching, of course, could give you
unlimited sigifigance as long as your set of values is repetitive, where
the aribitrary length floats would have signifigance and range proportionate to
their size...
with a set of calls like
float ConvertByteFloat(int Nbytes,char* ByteStream);
double ConvertByteFloat(int Nbytes,char* ByteStream);
real*4 function ConvertByteFloat(Nbytes,ByteStream)
integer*4 Nbytes
character*(*) ByteStream
real*8 ConvertByteDouble(Nbytes,ByteStream)
integer*4 Nbutes
character*(*) ByteStream
.... that is, of course, if these dont exist...?
