Displaystyle x and gives as output the greatest integer less than or equal to. Floor and ceiling functions problem solving problems involving the floor function of x x x are often simplified by writing x n r x n r x n r where n x n lfloor x rfloor n x is an integer and r x r x r x satisfies 0 r 1. In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.
