Function
(1) This instruction raises the 64-bit floating-point data type real number specified by to the
number nth specified by power, and then stores the operation result into the device
specified by .
(2) The following shows the values to be specified by and stored into or
0, 2-1022 | Set values (Storage values) | < 21024
(3) If the value resulted from the operation is 0 or an underflow occurs, the result will be
processed as 0.
QnU(D)(H)CPU: The serial number (first five digits) is "10102" or later.
QnUDE(H)CPU: The serial number (first five digits) is "10102" or later.
: Exponentiation recipient data or head number of the devices where the exponentiation recipient data are
stored (real number)
: Exponentiation data or head number of the devices where the data are stored (real number)
: Head number of the devices where the operation result will be stored (real number)
