推荐答案

您确定您的编译器不支持 64 位除法吗?如果您的 C 编译器支持 C99，这应该可以工作:

Are you positive your compiler doesn't support 64-bit division? If your C compiler supports C99, this should work:

#include <stdint.h>
#include <stdio.h>
int main(void)
{
    int64_t numerator = 123;
    int64_t denominator = 10;
    int64_t quotient = numerator / denominator
    printf("%" PRId64 " / %" PRId64 " = %" PRId64 "
",
           numerator, denominator, quotient);
    return 0;
}
