from spinhawk.
All production versions of Hercules up to 3.09 contain only a partial implementation of IEEE floating point (BFP in mainframe terminology). This partial implementation is known to produce incorrect results for certain operations. The development version of Hercules has addressed this problem by replacing the partial BFP implementation by calls to the softfloat package, which while slower does produce correct results. The modification has not yet been retrofitted into the production versions of Hercules but it is in the plan.
