mpfr

Is there a publically available library that will produce the exact same results for sin, cos, floor, ceil, exp and log on 32 bit and 64 bit linux, solaris and possibly other platforms? I am considering the following alternatives: a) cephes compiled with gcc -mfpmath=sse and the same optimization levels on each platform ... but its not clear that this would work. b) MPFR but I am worried that this would be too slow. Regarding precision (edited): For this particular application I don't really need something that produces the value that is numerically closest to the exact value. I just need the

I would like to serialize a custom class containing an boost::multiprecision::mpfr_float as a member. It says here in the Boost.Serialization documentation that a type T is serializable iff at least one of 5 properties is true, and here at the Multiprecision documentation that the number class has pass-through support which requires the underlying backend to be serializable. For Boost.Multiprecision's mpfr_float type, I know: It is not a primitive type. It is a class type, but it doesn't have the serialize function(s) defined. It is not a pointer to a Serializable type. It is not a reference

I a new C++ user and have only Visual studio 2008 installed. It seems from this link: Brian Gladman's Home Page There is already "Visual Studio 2010 project build files for building MPFR", which is only for VC2010 and my VS cannot open it. mpfr.svn.build.vc10.zip My questions are: 1) where can I find a version for VS2008? 2) or how can I produce it myself since there are already new updates of mpfr? project files for mpfr thank you! ######### Problem Solved Solution: download this pre-compiled mpfr and config VC complier will be OK! mpfr_mpir_x86_x64_msvc2010.zip It seems the pre-compiled mpfr
