data conversion cray to IEEE

Ing Meloni — Mon, 19 Nov 2001 09:45:18 GMT

One of my users presented me this problem: he runs on our HP-UX N servers a quantum physics
application that produces output in a binary 128-bit Cray format. To analyze and further work on the produced data he needs to convert them to a IEEE format. Online I found some conversion libraries, but they only support up to 64-bit data. Any hint or suggestion?
Obviously the user has no permission to modify the original code.

Is the output (to cray) numbers, like integers or floating point?

Take a look at:

or even better:
