完成需求I7KEB8，默认运算采用精度运算。

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。

(资料图)

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();}
