I don't know any reported bug of the decimal implementation (though PR 37845 about the FP_CONTRACT pragma, which affects binary on some machines, might also affect decimal in some distant future if it is still not fixed). But if you want an example, I don't think that the formatOf arithmetic operations (IEEE 754-2008 §5.4.1 -- that's a "shall") are implemented by GCC, either for binary or for decimal, say add two _Decimal128 numbers and round to _Decimal64 directly (with a single rounding). -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
