Precautions The Dividend (Dd to Dd+3) and Divisor (Dr to Dr+3) data must be in IEEE754
floating-point data format.
3-16-9 DOUBLE DEGREES TO RADIANS: RADD(849)
Purpose Converts a double-precision (64-bit) floating-point number from degrees to
radians and places the result in the specified result words.
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.

Error Flag ER ON if the dividend or divisor data is not recognized as
floating-point data.
ON if the dividend or divisor is not a number (NaN).
ON if the dividend and divisor are both 0.
ON if the dividend and divisor are both +∞ or –∞.
OFF in all other cases.
Equals Flag = ON if both the exponent and mantissa of the result are 0.
OFF in all other cases.
Overflow Flag OF ON if the absolute value of the result is too large to be
expressed as a double-precision floating-point value.
Underflow Flag UF ON if the absolute value of the result is too small to be
expressed as a double-precision floating-point value.
Negative Flag N ON if the result is negative.
OFF in all other cases.
