In the case of a software library , the code documents and user documents could be effectively equivalent and are worth conjoining , but for a general application this is not often true .

对于软件库来说，代码文件和用户文件在效果上是相同的，并且两者可以组合使用，但是对于综合应用，可能就不是这样了。

This will benefit a wide range of applications; motor control algorithms can be improved to allow the motor to run more silently or consuming less energy, sensor data can be filtered or analyzed to suppress noise and capture more useful information, and audio data can be processed without loss of fidelity. The 32-bit AVR UC3 Floating Point Unit is compliant with the widely accepted IEEE 754 standard. This ensures compatibility with a wide range of existing math libraries and application code.

这种技术有利于多种应用：对于电机控制应用，可以改善算法，让电机运行更安静或耗电更少；对于传感器应用，可过滤或分析数据，抑制噪声并撷取更多有用信息；对于音讯应用，可处理声音数据而不会失真。32位的AVR UC3 浮点单元与广泛被接受的IEEE 754标准兼容，可确保与现有的多种算法软件库和应用程序代码的兼容性。

Unfortunately, it's not in the Ubuntu repositories yet.

遗憾的是，Ubuntu软件库里还没有收录它。

In general you will only ever need to compile an application if it is not available from the repositories.

通常来讲你只有在一个应用程序在软件库里不可用的时候才需要编译。

They are able to use third-party repositories easily and do most everything as if they had a steady Internet connection.

他们可以很容易地使用第三方的软件库，并且可以像有互联网连接那样完成绝大多数的工作。
