In the function round of Display 3.6, which of these explains what happens in the body of the function? We reproduce the one line from the function body here: return static_cast(floor(number+0.5));

a. This is overkill, it would be sufficient to use the floor function alone. b. Adding 0.5 to number pushes the range up so floor can produce the correct rounding. c. The static_cast is used because floor returns a double. If the double value were returned, there would be at least a warning of a double to int conversion in returning the value. d. This is wrong. The argument for the floor function should be number-0.5.
