multiprecision modf
Hi Boost, Does Boost.Multiprecision provide modf for floating point types? I need it for generating with Karma, unless the fact that mpfr_float with variable precision not having numeric_traits might get in the way. Thanks for any help. Error message follows.

I haven’t looked into this in detail, but I think not, but Boost.Math does #include <boost/math/special_functions/modf.hpp> You might also need to add this to your local function(s) to aid Argument Dependant Lookup (ADL). BOOST_MATH_STD_USING http://www.boost.org/doc/libs/1_61_0/libs/math/doc/html/math_toolkit/config_... Table 11. Boost.Math Macros “Provides using statements for many std:: (abs to sqrt) and boost::math (rounds, modf) functions. This allows these functions to be called unqualified so that if <http://en.wikipedia.org/wiki/Argument-dependent_name_lookup> argument-dependent Argument Dependent Lookup fails to find a suitable overload, then the std:: versions will also be considered.” HTH Paul From: Boost-users [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Daniel Brake Sent: 03 August 2016 06:37 To: boost-users@lists.boost.org Subject: [Boost-users] multiprecision modf Hi Boost, Does Boost.Multiprecision provide modf for floating point types?

No it doesn't, and I'm not sure how/why we missed that one. A quick and dirty workaround would be something like: template <class T> T modf(T val, T* ipart) { *ipart = boost::math::trunc(val); return val - *ipart; } Meanwhile I guess I'd better go off and implement it properly.... John.
Thanks for any help. Error message follows.
