Division on rails 4

Question

I'm having a hard time on thinking what should I do with this problem. I'm dividing the two numbers and expecting a non-whole number answer. Meaning to say it should be on decimal format. But unfortunately it answers a whole number. example: 5 / 2 = 2

 s.apts =  sum_pts.to_f / sum_game.to_f

@YuHao it's not working on me. That's why I'm asking a help. — ana, Jan 27 '15 at 02:36
Provide a simple example of `sum_pts` and `sum_game` so that is can be reproduced. — Yu Hao, Jan 27 '15 at 02:39

You just need to tell Ruby you are doing non-integer division, by writing the problem as "5.0 / 2.0"

See:

Why is division in Ruby returning an integer instead of decimal value?

Try this:

a = 5.0
b = 2.0
puts a / b
