@javiermartinezruiz thank you for report.
We have created internal issue MAGETWO-59973

There is a workaround described in #7502 that we are using, but it involves editing a file in the Zend library (the file to edit might be different though between the Colombian and the Chilean Spanish locales).

Here is another option/workaround if you don't need multiple Spanish translations.

We are using this language pack: https://www.mageplaza.com/magento-2-spanish-language-pack.html

Instead of changing core files we installed the pack manually and changed the locale from es_AR to es_ES.

To do so change the following files/lines to:

registarion.php:

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::LANGUAGE,
    'mageplaza_es_es',
    __DIR__
);

language.xml:

<?xml version="1.0"?>
<language xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/Language/package.xsd">
    <code>es_ES</code>
    <vendor>mageplaza</vendor>
    <package>es_es</package>
</language>

php bin/magento cache:clean
php bin/magento setup:static-content:deploy es_ES

and select Spanish (Spain) as you store locale.

Hi! if you see when send a decimal in qty field (like 3.0) the add to cart work normally. I created a "Before plugin" for Magento\Checkout\Controller\Cart\Add and Magento\Checkout\Controller\Cart\UpdatePost intercepting the request and transforming the qty params to decimal.

Was the way I found to doesn`t change the Core. Maybe override the Controllers with Preferences is another quick solution.
