Real Floating Point的意思|示意

A real type defines a set of Numbers that can be represented with floating-point notation.

实数类型定义了一组可以以浮点记号描述的数。

In Part 2, I'll explore the functions more designed for operating on floating point Numbers as opposed to abstract real Numbers.

在第2部分，我将探讨专为操作浮点数(与抽象实数相反)而设计的函数。

Floating-point Numbers are not real Numbers.

浮点数并不是实数。

Real Programmers scorn floating point arithmetic. The decimal point was invented for pansy bedwetters who are unable to think big.

真正的程序员嘲笑浮点算法。小数点是为不会顺利思考的家伙发明的。

Floating-Point literals may also be represented using exponential notation: a real number followed by the letter e(or E), followed by an optional plus or minus sign, followed by an integer exponent.

此外，还可以使用指数记数法表示浮点型直接量，即实数后跟随字母e或E，后面加上正负号，其后再加一个整型指数。

The exponential function serves as a good example of how careful you have to be when dealing with limited-precision floating-point Numbers instead of infinitely precise real numbers. ex (Math.exp ).

指数函数是一个很好的例子，它表明处理有限精度浮点数(而不是无限精度实数)时是需要非常小心的。
