The COS instruction places the sine of the Source (in radians) in the
Destination.
Enter the following parameters when programming this instruction:
• Source is the address to compute the cosine.
• Destination is the address to store the cosine of the Source.
Address Levels for the operands involved in the COS can be ALL word,
ALL double word, ALL float, or a combination. These operands shall
undergo a conversion to float. The calculation of the source (in float) is
then performed, and the result is then cast to the data type of Destination.
