💰 Formatting Numbers with number_to_* Helpers

Rails provides a suite of helpers for number formatting like number_to_currency, number_with_delimiter, and more. They help present numbers in a user-friendly way.

<%= number_to_currency(@order.total_price, unit: '€', precision: 0) %>
<%= number_with_delimiter(1234567) %> <!--=> "1,234,567" -->
<%= number_to_percentage(0.256, precision: 1) %> <!--=> "25.6%" -->

These methods accept options for localization and precision to fit your needs.
