整型(INTEGER)数据是不包含小数部分的数值型数据,用字母I表示。整型数据只用来表示整数,以二进制形式存储。
如表1所示,Derby提供了对三种整型数据类型的支持。
As shown in Table 1, Derby provides support for three different integer data types.
然后是lld,我们等会就会看到,这个代表长整型数据,它是相当重要的,特别是当你需要,处理大量信息的时候。
And then LLD, we'll see in a moment, this is for particularly long Numbers which will become relevant especially as you're trying to process lots of information.
这种组合不可避免地使许多程序员忽视了数据类型(如整型和浮点)和基本数据结构(如列表和映射)的缺陷。
The combination was irresistible enough that programmers could overlook the lack of data types like int and float and basic data structures like lists and maps.
It just throws the decimal point away and that's because, again, these are ints and the answer intuitively should be a floating point value, but I need to be more specific.
它直接把小数点后面的数值丢弃掉了,因为,凭直觉,那些整型数和结果应该是一个浮点数据,但是我需要一个更精确的数值。
> Okay. Well, this code allocates a new integer pointee and this part sets x to point to it.
>,好的,呃,这段代码分配一个新的整型指针数据,这部分让x指向它。
