__inlineintsquare(int x) {returnx * x;#include doublelength(intx,int y){returnsqrt(square(x) + square(y));使用内嵌函数有几个优点：没有调用函数的开销。因为函数被直接代替，没有任何额外的开销，比如存储和恢复寄存器。更低的参数赋值开销。参数传递的开销通常会更低，因为它不需要复制变量。如果其中...

当Cython 支持更多的推断的时候,变量 i 被类型化为 C long;d 和之前一样是 double,而 c 和 r 都是复数变量,复数则依旧使用 Python 中的复数类型。但是注意:并不代表启用 infer_types 时,就万事大吉了;我们知道在不指定 infer_types 的时候,Cython 在推断类型的时候显然是采用最最保险的方法、在保证程序正确...

It is recommended that the variable declaration and each operation on that integer be clearly commented as supporting modulo behavior.[Impact]Integer wrapping is likely to cause buffer overflows and arbitrary code execution.Ensure that division and remainder operations do not cause divide-by-zero...
