#12198: cpp_bin_float addition/subtraction produces wrong result when the
difference of exponents of arguments overflows
------------------------------+----------------------------
 Reporter:  Michael Shatz     |      Owner:  johnmaddock
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  multiprecision
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------------
 If the difference of exponents of two cpp_bin_float does not fit in
 specified exponent_type then addition and subtraction
 operations return the operand with smaller exponent instead of operand
 with bigger exponent.

 Platform: Mingw, gcc 5.3.0, x64. All optimization levels.
 Library version: both 1.60.0 and the newest files from github
