Hello, Welcome to mpir-devel! The first thing that I can say is that MPIR on its own is not the best application to use for multiple precision floating point applications. The mpf functions work but they have now been superseded by another package called MPFR (see www.mpfr.org) that provides significant improvements for high precision floating point algorithms.
Although this requires yet another package to install, I think you will find that the extra effort will be worthwhile. In particular this will give you better control over precision and also allow long double conversions provided that your build environment supports this type (Microsoft build tools on Windows don't support long double). The second point I would make is that there are also C++ packages that allow high precision floating point types in a way that is essentially identical to ordinary double types - see, for example, the MPFRC++ ( http://www.holoborodko.com/pavel/mpfr/). These packages allows you to develop your code using ordinary doubles and, once it is working, you can then do a simple search and replace operation to convert 'double' into 'mpreal' and it will then work with high precision floating point types (a few other changes might be needed). Pavel's web page gives examples and you might also be interested in Rick Regan's 'Exploring Binary' where he explains how he went through the issue you are looking at here: http://www.exploringbinary.com/how-to-install-and-run-gmp-on-windows-using-mpir/ (he uses mpf types but I would recommend that you use MPFRC++ instead). He aslo gives examples that might help you. If you need more help, I would be happy to look at your code and offer advice on how to get it working with MPFRC++. If you have an email address, I will be willing to advise you off-line or you can continue to ask questions here. good luck, Brian Gladman -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
