DEG(459) converts the 32-bit floating-point number in S+1 and S from radians
to degrees and places the result in R+1 and R. (The floating point source data
must be in IEEE754 format.)

Radians are converted to degrees by means of the following formula:
Radians 180/ = degrees
If the absolute value of the result is greater than the maximum value that can
be expressed as floating-point data, the Overflow Flag will turn ON and the
result will be output as
If the absolute value of the result is less than the minimum value that can be
expressed as floating-point data, the Underflow Flag will turn ON and the
result will be output as 0.
