11.8。十进制浮点运算

The integer part, the optional decimal point and the optional fraction part form the significant part of the floating literal.

整数部分，可选的小数点，以及可选的小数部分组成浮点文字量的有效部分。

We can use either common decimal notation or scientific notation to write floating-point literal constants.

通常可以用十进制或者科学计数法来表示浮点字面值常量。

Floating-point numbers are defined as any number that contains a decimal fraction and that can be expressed in decimal or scientific notation, as shown in Listing 1.5

浮点型数值像任何包含一个小数的数那样定义，并且能用十进制或是科学计数法表示。如Listing 1.5所示

Whether the number is printed using decimal or scientific notation depends on the value of the floating-point number being printed. The library chooses a format that enhances readability of the number. Very large and very small values are printed using scientific notation. Other values use fixed decimal.

使用小数形式还是科学记数法显示数值取决于被显示的浮点数的值，标准库选择增强数值可读性的格式，非常大和非常小的值使用科学记数法显示，其他值使用小数形式。

A floating literal consists of an integer part, a decimal point, a fraction part, an e or E, an optionally signed integer exponent, and an optional type suffix.

浮点文字量由整数部分，小数点，小数部分，e或 E，可选的有符号整数指数，以及可选的类型后缀组成。

By default, when the fractional part of a floating-point value is 0, the decimal point is not displayed.

默认情况下，当浮点值的小数部分为 0 的时候，不显示小数点。

Translates a double into a BigDecimal which is the exact decimal representation of the double's binary floating-point value.

上面的API简要描述相当的明确，而且通常情况下，上面的那一个使用起来要方便一些。我们可能想都不想就用上了，会有什么问题呢？

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
