C++ 2017年VS中的标题cmath Intellisense错误

头cmath根本不起作用，当我在项目中打开cmath头文件时，VS Intellisense显示错误，如

全局范围没有“acosf”

，并且有数百个

我读了很多文章，但还没弄明白。我已经根据一个线程确认了我正在使用sdk 10.0.15063.0，但它不起作用

包括cmath在内的任何项目都不起作用，因此它可能与特定代码无关。我已经尽力了，你们能告诉我怎么解决吗？提前谢谢

完整的错误列表如下所示：

谢谢各位，我已经解决了这个问题。这是因为不同的<代码>数学冲突。H.<代码> >在包含目录>

中，你编译为C还是C++，它们是不同的语言。您应该展示一个导致问题的代码示例。看起来应该很短。包括，main，可能还有几行代码。非常感谢，我已经在上面添加了包含cmath的标题，希望这会有所帮助，但是当我打开一个新项目时，它也会显示相同的错误。它应该是编译c++“VS Intellisense显示错误”-它是Intellisense，代码可以编译吗？我不能复制/粘贴代码，所以我不能告诉你它是否适合我。如果你使用C++，你应该删除C标签。他们是不同的语言。
