Does anyone have any code to deal with ieee to cray (XMP) floating point numbers and back? We have an application that runs under several OS's, that can use ieee to most efficiently interchange data (ascii being the alternative). Source code would be preferred since we have to trap NaN's and deal with them separately. Thanks. -- Brian Glendenning INTERNET - brian@radio.astro.toronto.edu Radio Astronomy, U.

Please note however, the exponent range on the Cray is larger than IEEE double while the precision of IEEE double is greater than the Cray precision. You loose something either way. J.
