所以我在使用一些在单个产品页面上显示销售徽章的代码时遇到了问题。问题是徽章显示的百分比很差，我们需要将其四舍五入到精确的数字...现在它显示 40.2% 的销售额...我们需要它显示 40% 的销售额。
产品显示 40.2% 销售额的网站（只需选择 18.7 选项）：https://juvelyrine.lt/produktas/ranku-darbo-minimalistinis-auksinis-ziedas-18-d/

对我来说，代码看起来应该将其四舍五入，但事实并非如此......
您的代码中存在一些错误和遗漏的内容。这是您重新访问的代码，它将显示四舍五入的节省百分比

它应该按预期工作
