Interchange instruction between double-word integer and real number;

(a) An instruction to convert a double-word integer into a real number. (b) An instruction to "round" a real number into a double-word integer. (c) The instruction "Real numbers are converted into double hard skills, and the mantissa is rounded off".

(1), double-word integer to real number instruction. The ladder diagram of double-word integer conversion forced real instruction consists of mnemonic line HOLR, enabling signal (en integer input (N) and real output depth (ouD), and its statement table consists of operation code (OTR) integer input (in) and physical output (OU). The instruction to convert a double-word integer into a real number can convert a 32-bit signed integer into a 32-bit real number. When the signal EN 1 is enabled, double integers are converted into real numbers, and the result is transmitted to oUT.
