ABSTRACT:
A method, system and program product are provided for establishing one or more decimal floating point (DFP) operand for facilitating testing of a decimal floating point instruction. The method includes obtaining an encoded DFP operand previously generated for testing the decimal floating point instruction, and logically modifying at least one bit of the encoded DFP operand without decoding the encoded DFP operand to obtain an additional encoded DFP operand. In one embodiment, m sequential bits of the encoded DFP operand, n randomly generated bits (wherein n=m), and a logical operation (such as an AND, OR, XOR or SHIFT) are employed in modifying the previously generated, encoded DFP operand.
