Floating point and decimal Numbers are not nearly as well-behaved as integers, and you cannot assume that floating point calculations that "should" have integer or exact results actually do.

浮点数和小数不象整数一样“循规蹈矩”，不能假定浮点计算一定产生整型或精确的结果，虽然它们的确“应该”那样做。

It also has the first decimal floating-point unit integrated in silicon.

它还首次在芯片中集成了十进制浮点单元。

IEEE 754 represents floating point Numbers as base 2 decimal Numbers in scientific notation.

IEEE 754用科学记数法以底数为2的小数来表示浮点数。

youdao

There's no decimal point; there's no point zero; there's no floating point value, it's just a hardcoded integer.

这里没有小数点，这里没有;,这里没有浮点数值，它只是一个整型数字。

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。
