def roundnearest(multiple=10)
  (self/multiple.to_f).round * multiple
end

def roundnearest(nearest=10)
up = roundup(nearest)
down = rounddown(nearest)
if (up-self) < (self-down)
return up
else
return down
end
end

For example if I have modulus(5/2) I will get 1. modulus(10/7), I will get 3. In rails, this code would go in its own file under RAILS_ROOT/config/initializers/. Otherwise, you would just put this code in its own file and require it in your other source code.
