Synopsis

This class contains static toLocal functions to convert data from VAX format to local format and vice-versa. It only handles VAX D-float format. Another class should be implemented to handle VAX G-float format.

The functions work well on big-endian as well as little-endian machines.

Motivation

Archived WSRT data can be stored in the old VAX format (little-endian and VAX D-float floating point format). Conversion functions are needed to read these data.

To Do

Support data type long double.

VAXConversion()

This class should not be constructed (so declare the constructor private).
