#define CONVERT_MODCOMP_CHAR

Define for each data format if a conversion is needed from the ModComp format to the local format (or vice-versa).

This allows for optimizations in, for example, AipsIO.

The ModComp format is ASCII for strings, a proprietary floating point format and 2-complement for integers (all most significant bit first) with the lengths as shown above.

Change the definitions below if new architectures (whith different lengths for these integer types) are being used.

#define CONVERT_MODCOMP_DOUBLE

Definition at line 84 of file ModcompConversion.h.

#define CONVERT_MODCOMP_FLOAT

Conversion is always needed for floating point data.

#define CONVERT_MODCOMP_INT64

Definition at line 79 of file ModcompConversion.h.

#define CONVERT_MODCOMP_SHORT

Conversion is needed for little endian architectures (like DEC and Intel), because the bytes have to be swapped (thus not for data with length 1).

 Conversion is not needed for integers if the local lengths for Shorts and

Ints is 2,4 respectively.
