Precautions The source data in S+1 and S must be in IEEE754 floating-point data format.
3-15-14HIGH-SPEED COSINE: COSQ(476)
Purpose Calculates the cosine of a 32-bit floating-point number (in radians) and places
the result in the specified result words.
Note These instructions can be used in the CJ1-H-R CPU Units only.
