General description

This page describes the EAS3 file format. It is the product of a toolkit intended to help transfer floating point data between computers, to convert it to other formats and process it. It is intended to help deal with problems such as endianness and floating point implementation differences between computers. EAS stands for Ein Ausgabe System.

The format was designed by the Institut für Aerodynamik und Gasdynamik (IAG) of the Universität Stuttgart, and is described in their EAS3 web pages. (This site has an out-of-date certificate; it claims that a new wiki is under development but not yet available.)
