Hello,

I have a big problem.

On my online store, prices are in euros, and I use Fox Currency Switcher to convert them to different currencies. There are never any problems with euros, but with other currencies, there are sometimes issues (not all the time). The decimal point is misaligned. For example, a customer places an order for CA$49.90 + CA$209.90 worth of products + CA$122.21 shipping. That's a total of CA$382.01. The converted prices look normal on the product page and also on Stripe. I've even checked the Stripe logs, and everything is fine. But on the order page, there's an error. I've included a screenshot below. 49.90 becomes 499.00, 209.90 becomes 2099.00, and the delivery fee of 122.21 becomes 12221.00.

Our customers always panic when this happens and even dispute charges on their credit cards because of it.

Here is the code for rounding that I put in functions.php. Is it correct? Could it be the source of the problems?

// Arrondi des prix sauf pour HUF et EUR

add_filter('woocs_raw_woocommerce_price', function($price) {

global$WOOCS;

if (in_array($WOOCS->current_currency, ['HUF', 'EUR'])) {

return$price;

}

if (is_admin()) return$price;

$is_product_context = false;

if (is_product() || is_shop() || is_product_category() || is_product_tag()) {

$is_product_context = true;

}

if (did_action('woocommerce_before_calculate_totals')) {

$is_product_context = true;

}

if ($is_product_context) {

if ($price < 10) {

$rounded = round($price); // Arrondi à l’entier

} else {

$rounded = round($price / 10) * 10; // Arrondi à la dizaine

}

$adjusted = $rounded - 0.10;

returnmax(0, $adjusted);

}

return$price;

});

// Arrondi spécial pour la devise HUF à x90 HUF

add_filter('woocs_raw_woocommerce_price', function($price) {

global$WOOCS;

if ($WOOCS->current_currency !== 'HUF') {

return$price;

}

if (is_admin()) return$price;

$is_product_context = false;

if (is_product() || is_shop() || is_product_category() || is_product_tag()) {

$is_product_context = true;

}

if (did_action('woocommerce_before_calculate_totals')) {

$is_product_context = true;

}

if ($is_product_context) {

$rounded = round($price / 100) * 100;

$adjusted = max(0, $rounded - 10);

return$adjusted;

}

return$price;

}, 20);

Or is it because the euro uses commas to separate decimals and the Canadian dollar uses periods? I'm really lost.

Thank you for your help,

Camille
