Question

Which of these methods return a largest whole number less than or equal to variable X?

(a) double Ciel(double X)

(b) double Floor(double X)

(c) double Max(double X)

(d) double Min(double X)

I had been asked this question in an interview for internship.

My doubt is from Rounding Functions topic in division Reflections, Multithreaded Programming, Collection Classes and Mathematical Functions of C#

Answer 1

The correct answer is (b) double Floor(double X)

To explain I would say: double Floor(double X) returns a largest whole number less than or equal to variable X.
