I have the following float: 2.554 and I need to format as percentage using ruby/rails.
How to round down that float ? I tried to use number_to_percentage but the value is displayed as 2.6 (round up)

3`2.554.to_i #=> 2` or `2.554.floor #=> 2`. – Cary Swoveland Feb 21 '20 at 01:36

What is the expected output? `2.5`? `2`? – spickermann Feb 21 '20 at 06:53

To drop everything after 2 decimal places, use `2.555.truncate(2)` – Stefan Feb 21 '20 at 08:47

You cant use the round method specifying the number of digits to round. Sample
2.554.round(2)
=> 2.55
With the next variant you can force to round down if the third digit after comma is less than 5
2.555.round(2, half: :down)
=> 2.55
