Float formatting with decimals

I have a number charge.amount, whose value is 1900. I have a piece of ruby code like this:

charge.amount/100.to_f

The output is:

19.0

How do I display it with two decimal points like so:

19.00

The solution above works, but rounds the hundredth. Like so: 19.01 => 19.00

This works better to include hundredth of a cent:

sprintf('%.2f', charge.amount/100.to_f)

Like so => 1901 => 19.01

You can use rails helper like:

number_with_precision(charge.amount/100, precision: 2)

In Rails, you can use number_with_precision helper:

<%= number_with_precision(charge.amount/100, precision: 2) %>
