#12196: cpp_bin_float: convert_to<double> of infinity and NaN returns zero

 Reporter:  Michael Shatz     |      Owner:  johnmaddock
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  multiprecision
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------------
 Applying convert_to<double>() to cpp_bin_float object with values of Inf
 and/or NaN returns 0.
 That is a new bug in the latest github version.

 In Version 1.60.0 behavior is also not 100% correct, but better:
 inf.convert_to<double>() => 1.79769e+308
 nan.convert_to<double>() => nan

 Platform: Mingw, gcc 5.3.0, x64. All optimization levels.
