Hello again ( a lot of questions i know )

In my array i want to compare each value in that array to a certain range, for example, if a number in that array is between two certain values, e.g between 1-2, i want that number which falls in between that range to display another value. So if that number was 1.5 it would display a 1 instead, if it were at 1.8 it would display 1 as well. How do i compare my whole array to suit a certain range and then display a given variable for the respective range.
