28379D调用math.h中的正余弦函数,其中
#define sin __relaxed_sin
__inline double __relaxed_sin(double x)
{
return __sin(x);
}
#define cos __relaxed_cos
__inline double __relaxed_cos(double x)
{
return __cos(x);
}
与
_CODE_ACCESS double cos(double x);
_CODE_ACCESS double sin(double x);
二者有何不同?

我们会在确认后给您回复。

Susan Yang:
两者的区别如下:
The relaxed implementation I believe refers to the faster, but less accurate implementation on the TMU.
