hi all, is there a c++/boost.math way to find the highest representable floating point number lower than a certain limit ... something like boost::supremum<float>(1.f)? thanks, tim -- tim@klingt.org http://tim.klingt.org Avoid the world, it's just a lot of dust and drag and means nothing in the end.

Do you mean as in the C99 function nextbefore? It's not in Boost.Math currently, but really should be, might not be too hard to implement either I suspect... John.

oh, i wasn't aware of the c99-style nextafter-style functions ... although i'd like to see a c++ implementation, the c99-style functions should be ok for me for now ...

i would really like to see them in boost.math ... i'll file a feature request in the tracker ... thanks, tim -- tim@klingt.org http://tim.klingt.org Question: Then what is the purpose of this "experimental" music? Answer: No purposes. Sounds. John Cage
