3.22.4.2 Functionality
The real subtraction function SUBR subtracts input REAL_IN2 from REAL_IN1.
SUBR executes the equation
REAL_OUT = REAL_IN1 – REAL_IN2
If the value of the difference is outside the range, then the output quality is
set as bad and VALID is set to FALSE. The minimum negative difference value is
restricted to –2097152.000 and the maximum positive difference value is restricted
to 2097152.000.
