Hi, I can’t find out how to convert each integer in my array to a float.  
I’ve tried:

array.each {|x| x.to\_f}

But it did not work.

Can anyone tell me the correct method?

array.map! { |x| x.to\_f } # for in place modification  
array2 = array.map { |x| x.to\_f } # if you want a new array with  
float values without messing up the old array
