java保留两位小数问题: 方式一: 四舍五入 double f = 111231.5585; BigDecimal b = new BigDecimal(f); double f1 = b.setScale(2, BigDecimal.ROUND_HALF_UP).doubleValue(); 保留两位小数 --------------------------------------------------------------- 方
If IsNull({DECL_INV_ITEM_I.DECLEAR_NO}) Or Trim({DECL_INV_ITEM_I.DECLEAR_NO}) = "" Then "0" Else CStr({DECL_INV_ITEM_I.EX_RATE},5,',') CSTR({number_field}, 0, ''),第一个是数字字段:第二个是保留的小数位,0是整数:第三个是千分位分隔字符.
