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+3CH S+2CH S+1CH
D+3CH D+2CH D+1CH
Degrees are converted to radians by means of the following formula:
Degrees /180 = radians
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.

.
Operation
ON if the source data is not recognized as floating-point
data.
ON if the source data is not a number (NaN).
OFF in all other cases.
ON if both the exponent and mantissa of the result are 0.
OFF in all other cases.
ON if the absolute value of the result is too large to be
expressed as a double-precision floating-point value.
ON if the absolute value of the result is too small to be
expressed as a double-precision floating-point value.
ON if the result is negative.
OFF in all other cases.
