I want to be able to change the uom in the shopping cart at meter with 0.1 steps. So this means I want to add for example 0.2 meter of a product in the shopping cart. Originally I had 1 meter in the shopping cart and now I want to adjust to 1.2 meter. If I do that it will go back to 1 meter.

Here is a image for the better explanation: https://imgur.com/a/HnHiijI

I have found something in the java script code:

website_sale.js

var default_price = parseFloat($dom.find('.text-danger > span.oe_currency_value').text());

When I chance to "int" it doesn't work either because the refresh. This is a java-script problem and I'm not a developer anyway.

    /**
     * @private
     * @param {Event} ev
     */
    _onChangeCartQuantity: function (ev) {
        var $input = $(ev.currentTarget);
        if ($input.data('update_change')) {
            return;
        }
        var value = parseInt($input.val() || 0, 10);
        if (isNaN(value)) {
            value = 1;
        }
        var $dom = $input.closest('tr');
        var default_price = parseFloat($dom.find('.text-danger > span.oe_currency_value').text());
        var $dom_optional = $dom.nextUntil(':not(.optional_product.info)');
        var line_id = parseInt($input.data('line-id'), 10);
        var productIDs = [parseInt($input.data('product-id'), 10)];
        this._changeCartQuantity($input, value, $dom_optional, line_id, productIDs);
    },
    /**
     * @private
     * @param {Event} ev
     */
    _onClickSuggestedProduct: function (ev) {
        $(ev.currentTarget).prev('input').val(1).trigger('change');
    },
    /**
     * @private
     * @param {Event} ev
     */

Does anyone has an idea how to fix this?

Thank you for your answers,
