Rails currency with 2 decimal

Question

Following were my HomeController:

def index
  @products = Product.public_active
                     .order('random()')
                     .limit(6)
                     .includes(:product_attachments)
                     .includes(:product_reviews)

  @products.each do |product|
    if product.currency != session[:currency]
      if session["currency-convert-#{product.currency}"].to_f == 0.0
        rate = 1.0  
      else
        rate = session["currency-convert-#{session[:currency]}"].to_f / 
               session["currency-convert-#{product.currency}"].to_f
      end
    else
      rate = 1.0
    end

    product.price_with_currency = 300.00
    product.current_currency = session[:currency]
  end
end

And here is my View:

<div id="product-list">
                <div class="row">
<p class="price"><%= product.price_with_currency %></p>
</div>
</div>

The issues is, price_with_currency output the result of 300.0 not 300.00. Why it is so? Thanks!!

@Albin in view? something like this `<%= product.price_with_currency, :precision => 2 %>` ? — d3bug3r, Mar 30 '16 at 05:54

You could use a helper called: number_with_precision

it would look like this:

<p class="price"><%= number_with_precision(product.price_with_currency, :precision => 2) %></p>

You can also use number_to_currency helper

For eg.

<%= number_to_currency(300, :unit => "$ ", :separator => ".", :delimiter => ",") %>

## Output
$ 300.00

Try to use either the two:

<p class="price"><%= number_with_precision(product.price_with_currency, precision: 2) %></p>

OR

<p class="price"><%= number_to_currency(product.price_with_currency, unit: "USD", precision: 2) %></p>

if you want currency with it :D like this USD 3,000.00 #if 3000
