Using number_to_currency with user parameter

My code

<td><%= number_to_currency(x['quote']['USD']['price'], :unit => '$', :separator =>'.', :delimiter => ',', precision: 4)  %><br/></td>

When I use it just like that, it is ok, extract the info and put it ok. But when I try to multiply with another variable, it send me an error "ActiveSupport::SafeBuffer can't be coerced into BigDecimal", so I was thinking in turn it into a @, but I am not sure how to do it

You could think number_to_currency returns a special string (e.g. "$ 123.0000"), it can't be multiplied with number directly.

You could multiply first, then use number_to_currency to format result:

<% result = x['quote']['USD']['price'] * crypto.cost_per %>
<td><%= number_to_currency(result, unit: '$', separator: '.', delimiter: ',', precision: 4) %></td>
