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.

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.
