最后将所有的浮点数据进行量化。
区别在于一个事实:计算机中使用的浮点数据类型无法包含每个实数。
The difference lies in the fact that floating-point data types used in computers can't hold every real number.
DECIMAL数据类型需要的存储空间通常要比浮点数据类型大得多。
The storage required for a DECIMAL data type is potentially much larger than it is for a normal floating-point data type.
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。
The reason I want to point this out to you is, if we go back up to the kinds of data objects we started with, floats, ints, strings, they actually behave the same way.
我要为大家指出这一点的原因是,如果我们想一下以前讲过的,数据类型的种类,浮点数,整数,字符串,它们实际上有相同的行为方式。
So a floating point value again is a number with a decimal point, so it depends.
一个浮点型数据就是一个,带小数点的数。
