对C99中复数的操作 [英] operations on complex numbers in C99

问题描述

据我所知，C99支持复杂类型和复杂的
算术。在常见问题解答和网上没有任何关于它的内容

搜索除了概要之外几乎没有。任何人都可以指向

我的消息来源或举例说明如何：


-declare一个复杂的变量

-分配实部和虚部

-执行复数上的基本+， - ，*，/操作


谢谢，

David

在常见问题解答中没有任何关于它的信息，除了大纲之外，在线搜索非常有用。任何人都可以指向我的消息来源或给出

示例，其中显示如何：


-declare一个复杂的变量

-分配实部和虚部

-执行复数上的基本+， - ，*，/操作

我见过的唯一例子是在标准的附录G中，而不是最好的（在标准中说话！），但它们应该足以让你获得
。

尝试N1124和/或N869。您可以通过以下方式获得BZ2'文本形式的N869：

I understand that C99 supports a complex type and complex
arithmetic. There is nothing about it in the FAQ and online
searches turned up very little except synopses. Can anyone point
me toward sources or give examples which show how to:

-declare a complex variable
-assign the real and imaginary parts
-perform the basic +,-,*,/ operations on complex numbers

Thanks,
David

The only examples I have seen are in Annex G of the standard, not the
best (being in standards speak!), but they should be enough to get you
going.

Try N1124 and/or N869. You can get N869 in BZ2''d text form from:
