Oracle COS() function
Description
The COS() function is used to get the cosine of a number where the number is given in radians.
The function takes any numeric or nonnumeric data type (can be implicitly converted to a numeric data type) as an argument.
If the argument is BINARY_FLOAT, then the function returns BINARY_DOUBLE. Otherwise, the function returns the same numeric data type as the argument
