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.
