  Dump constant double to file stream in binary format.

  Specified by:
    `dump` in class `Constant`
  Parameters:
    `file` - Output file stream
  Throws:
    `java.io.IOException`

### getBytes

    public final double getBytes()

  Returns:
    data, i.e., 8 bytes.

### setBytes

    public final void setBytes(double bytes)

### toString

    public final java.lang.String toString()

  Overrides:
    `toString` in class `Constant`
  Returns:
    String representation.

### getConstantValue

    public java.lang.Object getConstantValue(ConstantPool cp)
