Which of the following will produce an answer that is closest in value to a double, d, while not being greater than d?
Answer: D
The casting to an int is a smokescreen. Use a process of elimination to answer this question:
Option D is the correct answer, it is syntathecially correct and will consistently return a value less than d.
Option A and B are wrong because both the min() and max() methods require 2 arguments whereas here they are passed only one parameter.
Option C is wrong because it could return a value greater than d (if d was negative).
