== Description

* If `rhs` is signaling NaN, then store the value of the macro `EDOM` into `errno` and return a NaN. * Otherwise if `rhs` object is NaN, then return a NaN. * Otherwise if `rhs` is infinity, then return infinity. * Otherwise if the sum of `lhs` and `rhs` has an absolute value that is larger than `std::numeric_limits<Decimal32>::max()` then store the value of the macro `ERANGE` into `errno` and return infinity with the same sign as that result. * Otherwise return the sum of `lhs` and the number represented by `rhs`.
