long double, C, fortran
...can get that precision back. I have a few questions: 1. Does this affect the portability to other OSs or processors? 2. I'm returning the results in a matrix. Will a matrix of REALs be sufficient for holding long doubles, or will it be cast back to doubles? 3. Will calls to FORTRAN BLAS (like dsymv, dpotrf, dpotri) still work with long doubles? Thanks for any help you can provide. -- Richard D. Morey Assistant Professor Psychometrics and Statistics Rijksuniversiteit Groningen / University of Groningen http://drsmorey.org/research/rdmorey
