如何在grails中正确保存双精度类型？

基本上，要保存的域不尊重浮点，因为它使它成为另一种格式

我有下一个域名

class Location {
    double latitude
    double longitude
    static belongsTo=[ product: Product ]   
    static constraints = {      
        latitude nullable:false, blank:false
        longitude nullable:false, blank:false       
    }
}

视图：

请求位置保存（）的步骤

参数的到达方式类似于纬度参数=29.089177和经度参数=-110.961227 保存后，这些值存储在数据库中，如locationInstance.latitude=29089177和locationInstance.longitude=-110961227

要在视图中显示的内容类似于纬度=2.9089177E7和经度=-1.10961227E8

问题是，我有另一个主题类的项目，并且运行正常。 并尝试将属性和类型的名称更改为float和not resolved

谢谢

只需将其添加到conf/spring/resources.groovy中即可

beans = {
    localeResolver(org.springframework.web.servlet.i18n.SessionLocaleResolver) {
        defaultLocale = new Locale("es","MX")
        java.util.Locale.setDefault(defaultLocale)
    }
}

要保留坐标格式，请确保​​保存时不会更改。

准备就绪！基本上，要保存的域不尊重浮点，因为它使其成为另一种格式，可以是什么？显示实际的
