曼德尔布罗特麻烦 [英] Mandelbrot trouble

问题描述

前段时间我为一个非常简单的Mandelbrot资源管理器编写了这段代码。我遇到的主要问题是，在放大到一定深度后，我使用的双数据类型无法进一步发展。有没有办法解决这个问题？谢谢。

Hi,
I wrote this little piece of code for a very simple Mandelbrot explorer some time ago. The main problem I came across was that after zooming in to a certain depth, the double data type I used couldn''t go further. Is there a way to solve this problem? Thank you.

你可以做两件事之一。当你到达那里时，使用一个长的双，或找到重复的模式然后回到那个位置。


长双倍肯定更容易。

You can do one of two things. Use a long double, or find the repeating pattern and back off to that position when you get there.

The long double is definitely easier.

一定要做一个sizeof（long double）。在Windows上，double和long double是相同的。

Be sure to do a sizeof(long double). On Windows, double and long double are the same.

确保执行sizeof（long double）。在Windows上，double和long double是相同的。

Be sure to do a sizeof(long double). On Windows, double and long double are the same.

是的。你是对的。实际上我在我的代码中使用了long double，但后来我发现double和long double只有8个字节长。我说双，因为没关系。但是，有另一种解决方法吗？

Yep. You are right. Actually I used long double in my code, but later I found out that both double and long double are only 8 bytes long. I said double because it doesn''t matter. However, is there a way around this problem in another way?
