java.lang.Object
com.softwaremining.wrappers.format.Format
com.softwaremining.wrappers.format.AbstractNumericFormat
com.softwaremining.wrappers.format.NumericFormatFloat
public final class NumericFormatFloat extends AbstractNumericFormat
Used for representation of COMP_2 and COMP_4 variables. COMPUTATIONAL-4 or COMP-4 Specified for internal floating-point items (single precision). COMP-4 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.

    • getStorageCellSize

      public final int getStorageCellSize()
      Description copied from class: Format
      This is the number of characters in field.
      For example, PIC X(10) will have 10 characters
      or PIC 9(16) will have 16 characters
      but PIC 9(16) COMP-3 will have 8 characters
      Specified by:
