public final class NumericFormatDouble extends NumericFormatCompressed
Used for representation of DOUBLE PERCISION COMP_1 and COMP_2 variables. Default behaviour is for it to save in IEEE standards COMPUTATIONAL-1 or COMP-1 Specified for internal floating-point items (single precision). COMP-1 items are 4 bytes long. The sign is contained in the first bit of the leftmost byte and the exponent is contained in the remaining 7 bits. The last 3 bytes contain the mantissa. COMPUTATIONAL-2 or COMP-2 Specified for internal floating-point items (double precision). COMP-2 items are 8 bytes long. The sign is contained in the first bit of the leftmost byte and the remaining 7 bits contain the exponent. The remaining 7 bytes contain the mantissa.

      public final String convertFromCompressedStorageToDisplayFormat(String formattedString)
      Description copied from class: NumericFormatCompressed
      Convert from Storage-Compressed to Display This methods returns the actual stored value, even it is bigger than the defined format.
      E.g. PIC 9(2) COMP can store a value of 30000 ! This method will return "30000", but convertFromStorageToDisplayFormat will return "30".
