Twig

format_money

The Money counterpart of Twig's format_currency:

{{ product.price|format_money }}          {# 1 234,50 $ in fr_CA, CA$1,234.50 in en #}
{{ product.price|format_money('en_CA') }} {# $1,234.50 #}
{{ null|format_money }}                   {# nothing #}

The filter formats with ICU's currency pattern for the locale, to the currency's own precision. Its digits reach ICU as a float, exact up to 2^53 minor units — about 90 trillion dollars. One formatter is built per locale and kept, for 64 locales at most, so that locales taken from requests cannot grow the memory of a worker that lives across requests; the separators LocalizedDecimal reads for the forms are kept the same way.

With format_currency

An application that already uses twig/intl-extra can format a Money with its filter, from the decimal:

{{ product.price.toDecimal|format_currency(product.price.currency.code) }}

format_money saves the two property reads, and works without twig/intl-extra.

The data composes into a JSON-LD document printed by the template:

<script type="application/ld+json">{{ data|json_encode(constant('JSON_UNESCAPED_SLASHES') b-or constant('JSON_UNESCAPED_UNICODE') b-or constant('JSON_HEX_TAG'))|raw }}</script>

JSON_HEX_TAG writes < and > as escapes, so no value can close the script element.
