问题描述

如何将23.1这样的双精度转换为字符串？我不想使用

任何库函数，因为代码是用avr-gcc编写的，而我是/ b $ b不喜欢dtostrf（）的方式已经实施。谢谢。

Hi,

How can I convert a double such as 23.1 to a string? I don''t want to use
any library functions because the code is being written in avr-gcc and I
don''t like the way dtostrf() has been implemented. Thanks.

不知道avr-gcc和dtostrf是什么。但是，您考虑过

sprintf吗？

Don''t know what avr-gcc and dtostrf are. However, have you considered
sprintf?

我会参考PJ Plauger，_标准C库_。

另外，请阅读sprintf的GNU libc实现（但

你不喜欢它。）

我希望有一天能学会阅读。

似乎比写作更难。

I would refer to P.J. Plauger, _The Standard C Library_.
Alternatively, read the GNU libc implementation of sprintf (but
you won''t like it.)

我不能使用sprintf因为avr-gcc版本不支持
（它是编译器）。我只对某些手册感兴趣

的方式有效地进行双字符串转换。谢谢

Ben Pfaff写道：

I can''t use sprintf because it''s not supported by the version of avr-gcc
(it''s a compiler). I''m only interested in some "manual" way of
efficiently carrying a double to string conversion. Thanks
