Abstract
Processing within a computing environment is facilitated. An operand of an instruction is obtained, which includes decimal floating point data encoded in a compressed format. An operation is performed on the operand absent decompressing a source value of a trailing significand of the decimal floating point data in the compressed format.
Claims20
A computer system to facilitate processing in a computing environment, the computer system comprising:
- a memory;
- and
- a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
- obtaining an operand of an instruction, the operand including decimal floating point data encoded in a compressed format;
- and
- performing an operation on the operand absent decompressing a source value of a trailing significand of the decimal floating point data encoded in the compressed format.
A computer program product to facilitate processing in a computing environment, the computer program product comprising:
- a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
- obtaining an operand of an instruction, the operand including decimal floating point data encoded in a compressed format;
- and
- performing an operation on the operand absent decompressing a source value of a trailing significand of the decimal floating point data encoded in the compressed format.
A computer-implemented method of facilitating processing in a computing environment, the computer-implemented method comprising:
- obtaining, by a processor, an operand of an instruction, the operand including decimal floating point data encoded in a compressed format;
- and
- performing an operation on the operand absent decompressing a source value of a trailing significand of the decimal floating point data encoded in the compressed format.
