RADD(849) converts the double-precision (64-bit) floating-point number in
words S to S+3 from degrees to radians and places the result in words D to
D+3. (The floating point source data must be in IEEE754 format.)
S+3 S+2 S+1
D+3 D+2 D+1
Degrees are converted to radians by means of the following formula:
Degrees /180 = radians
