Operand Specifications
Description 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/π = 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.
