Synopsis

This class contains static toLocal functions to convert data from Modcomp format to local format and vice-versa.

The functions work on both big-endian and little-endian machines. They convert between Modcomp 2-byte integers and Shorts (or uShorts) and Modcomp 4-byte integers and Ints (or uInts, Int64s or uInt64s).

It is currently not possible to convert floating point numbers from local format to Modcomp. Attempting to do so will throw an exception (AipsError).

Motivation

The VLA data is stored using Modcomp numeric data formats and needs to be converted to the local format to be manipulated.

To Do

Support conversion of floating point data to Modcomp format
Support data type long double.

static uInt fromLocal(void* to, uInt64 from)
static uInt fromLocal(void* to, Float from)
static uInt fromLocal(void* to, Double from)

Convert one value from local format to Modcomp format. The from and to buffer should not overlap. The floating point functions will throw exceptions as they are not implemented yet.

static uInt fromLocal(void* to, const Float* from, uInt nr)
static uInt fromLocal(void* to, const Double* from, uInt nr)

Convert nr values from local format to Modcomp format. The from and to buffer should not overlap. The floating point functions will throw exceptions as they are not implemented yet.
