calculates the cosine of that number. Stores the result in the destination floating-point
data register. This function is not defined for source operands of infinity. If the source
operand is not in the range of [ – 2 ... + 2 ], then the argument is reduced to within that
range before the cosine is calculated. However, large arguments may lose accuracy
during reduction, and very large arguments (greater than approximately 10
accuracy. The result is in the range of [ – 1... + 1].
NOTES:
1. If the source operand is a NAN, refer to 1.6.5 Not-A-Numbers for more information.
2. Sets the OPERR bit in the floating-point status register exception byte.
