Getting Floored With 28 (Posted on 2008-09-06) Difficulty: 2 of 5
The greatest integer ≤ Y is denoted by [Y] , and {Y} = Y - [Y].

How many distinct real Y satisfy this equation, whenever 1 ≤ Y ≤ 28 ?

                                         {Y2} = {Y}2

Note: While a solution may be trivial with the aid of a computer program, show how to derive it without one.
