    IPC: G06F7/491

    Abstract: An instruction to perform a shift and divide operation is executed. The executing includes shifting a value in a specified direction by a selected amount to provide a dividend, the selected amount being user-defined. The dividend is divided by a divisor to obtain a quotient. At least a subset of the quotient is selected as a result. The result is to be used in processing within the computing environment.

    Abstract: An instruction to perform a multiply and shift operation is executed. The executing includes multiplying a first value and a second value obtained by the instruction to obtain a product. The product is shifted in a specified direction by a user-defined selected amount to provide a result, and the result is placed in a selected location. The result is to be used in processing within the computing environment.

    IPC: G06F9/30

    Abstract: Machine instructions, referred to herein as a long Convert from Zoned instruction (CDZT) and extended Convert from Zoned instruction (CXZT), are provided that read EBCDIC or ASCII data from memory, convert it to the appropriate decimal floating point format, and write it to a target floating point register or floating point register pair. Further, machine instructions, referred to herein as a long Convert to Zoned instruction (CZDT) and extended Convert to Zoned instruction (CZXT), are provided that convert a decimal floating point (DFP) operand in a source floating point register or floating point register pair to EBCDIC or ASCII data and store it to a target memory location.

    IPC: G06F8/41

    Abstract: Negative zero control for execution of an instruction. A process obtains an instruction to perform operation(s) using an input value. The instruction includes a negative zero control indicator indicating whether negative zero control is enabled for execution of the instruction. The process executes the instruction, the executing including performing the operation(s) using the input value to obtain a result having a sign, determining whether to control the sign of the result, the determining being based at least in part on the negative zero control indicator being set to a defined value, and performing further processing, as part the executing the instruction, based on the determining.
