How to sort an array of floats in Ruby?

Question

Just wondering how to sort an array of floats in Ruby, since "sort" and "sort!" only work for integer arrays.

Answer 1

Arrays of floats can certainly be sorted:

>> [6.2, 5.8, 1.1, 4.9, 13.4].sort
 => [1.1, 4.9, 5.8, 6.2, 13.4] 

Maybe you have a nil in your array, which can't be sorted with anything.
