Beetl 模板引擎 3.15.7 发布，Java 模板引擎

完成需求I7KEB8，默认运算采用精度运算。

【资料图】

Beetl默认情况下当遇到数字以h结尾的时候，认为是BigDecimal类型，随后运算使用高精度运算。

var a= 3434.33h*233334;

新版本增加配置,不允许显示的使用h表示高精度类型

BIGDECIMAL=true

则默认所有数字都翻译成BigDecimal

Script script = groupTemplate.getScript("return 5/3;",loader);script.execute();if(script.isSuccess()){Object value = script.getResult().get("return");Assert.assertTrue(value instanceof  BigDecimal);Assert.assertEquals(value,new BigDecimal(5).divide(new BigDecimal(3),ALU.scale, ALU.round ));}else{Assert.fail();}

Beetl.reflect 是指Beetl能像Java反射那样能查询出表达式结构，变量名
