FIELD: physics, computer engineering.
SUBSTANCE: group of inventions relates to computer engineering and can be used to convert data. The method includes steps of obtaining, by a processor, a machine instruction for execution, wherein the machine instruction is defined for execution by the processor according to computer architecture and includes at least one operation code field which provides an operation code, the operation code identifying a conversion function from a zoned from decimal floating-point; a first register field defining a first operand cell; a second register field and a displacement field, wherein contents of a second register defined by the second register field are combined with contents of the displacement field to form an address of a second operand; and a sign directive used to indicate whether the second operand has a sign field; and executing the machine instruction, which includes converting the second operand in a zoned format to a decimal floating-point format; and placing the conversion result in the first operand cell.
EFFECT: high efficiency.
