#10831: ublas OneElement returns 0.0

 Reporter:  r.r.ottenhoff@…   |      Owner:  guwi17
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  uBLAS
  Version:  Boost 1.57.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 In ublas::detail::concepts.hpp the function
 <template class T>
 OneElement(T)
 {
    return T(0.0);
 }
 returns 0 for all types. In older versions the function returned 1.f 1.
 for floats and doubles etc.

 This breaks some client code. In my case the Mkl bindings (Math Kernel
 Library of Intel) for ublas.
