没有十进制数这样的东西。数字是数字。但是
大概你的意思是你希望用十进制
表示法显示一个数字，你对格式说明符的引用表明你希望
使用printf执行此操作。
如果您有int类型，请使用％d或％i。对于short int和long int，应用
相应的修饰符，如C book中所列（在K& R2中，它们是在
第244页）。对于unsigned int类型，请使用％u而不是％d或％i。
如果要显示浮点类型，请使用％f。
There is no such thing as a "decimal number". Numbers are numbers. But
presumably you mean that you wish to display a number using decimal
notation, and your reference to a format specifier suggests that you wish
to do this using printf.
If you have an int type, use %d or %i. For short int and long int, apply
the appropriate modifiers, as listed in your C book (in K&R2 they''re on
page 244). For unsigned int types, use %u rather than %d or %i.
If you wish to display a floating point type, use %f.
也请告诉我截断十进制数的语法
also please tell me the syntax for truncating a decimal number
这取决于你的意思截断"以及你希望截断什么类型的价值（特别是关于你是否希望将存储的值兑换成
，或仅仅是显示的值）。

This depends on what you mean by "truncate" and on what type of value you
wish to truncate (and particularly on whether you want the stored value to
be truncated, or merely the displayed value).

一个小问题。标准确实使用术语十进制数和在strftime（）的
部分。它的含义正是你所写的关于
显示的内容，但我会避免写出没有这样的东西......
你知道总有一个例外。 ;-)
A tiny point. The Standard does use the term "decimal number" in the
section on strftime(). Its meaning is exactly what you wrote about
display, but I would avoid writing that there is no such thing as ....
You know that there is always an exception. ;-)

标准使用术语十进制数的事实并不意味着
有十进制数这样的东西。它只是意味着编写标准部分的人们认为这样的事情会产生这样的结果：
十进制数。

The fact that the Standard uses the term "decimal number" does not mean
there is such a thing as a decimal number. It merely means that the people
who wrote that part of the Standard think there is such a thing as a
decimal number.
