COS(461) calculates the cosine of the angle (in radians) expressed as a 32-
bit floating-point value in S+1 and S and places the result in R+1 and R.
(The floating point source data must be in IEEE754 format.)

Specify the desired angle (–65,535 to 65,535) in radians in S+1 and S. If the
angle is outside of the range –65,535 to 65,535, an error will occur and the
