Functionality

The real addition function ADDR adds the inputs REAL_IN1 and REAL_IN2
together. ADDR executes the equation
REAL_OUT = REAL_IN1 + REAL_IN2
If the value of the sum is outside the range, then the output quality is set as bad and
VALID is set to FALSE. The minimum negative sum value is restricted to
-2097152.000 and the maximum positive sum value is restricted to 2097152.000.
