Another factor to consider is the reliability of the routines that convert between decimal data and binary floating-point. Some conversion routines are very poor, and don't produce correctly rounded results for all values (as do the routines on z/OS). Even if identical instruction sequences and precisions are used for your computations, your input or output data may be corrupted, making the results look different.
