#4255: Documentation: No overflow-checking in accumulators, no precision
guarantees

 Reporter:  Tim Odenthal  |       Owner:  eric_niebler
     Type:  Bugs          |      Status:  new         
Milestone:  Boost 1.43.0  |   Component:  accumulator 
  Version:  Boost 1.44.0  |    Severity:  Problem     
 Keywords:                |  
--------------------------+-------------------------------------------------
 As discussed here[http://old.nabble.com/-accumulators--Is-there-a-reset-

 function-yet--td28635232.html], I suggest changing the documentation to
 warn users of possible overflow/loss of precision issues:

 Maybe in the section "The Accumulators Framework" one could add the
 sentence

 ''To ensure maximum performance, the predefined accumulators in the
 library do not check for possible overflows or loss of precision by adding
 numbers of very different exponents.''
