Better use custom PropertyEditor in order not to bother with formatNumber tag every time you output a value. Like, declare a bean in resources.groovy:

    void registerCustomEditors(PropertyEditorRegistry registry) {
        registry.registerCustomEditor(BigDecimal.class, new MyBigDecimalEditor(BigDecimal.class))
    }
}
