> Reviewing BinaryFileFunctions.java method convertDoubleToByteArray and convertDoubleArrayToByteArray there are two blocks of code, one for BYTE_ORDER_MOTOROLA (big endian) and one for BYTE_ORDER_INTEL (little endian).  These are backwards.  
> The convertByteArrayToDouble, on the other hand appears to be correct.  A reasonable test procedure would be to see if these two sets of methods are mutually consistent.
> The same problem appears to be the case for the "Float" variants, but not the Integer variants.
