整数除法的取整方式(Integer division rounding):在C语言中,对两个整数进行除法运算时,结果会向下取整,可能会导致精度丢失和错误的结果。 精度问题(Precision issues):在C语言中,浮点数的精度可能会受到舍入误差和截断误差的影响,导致计算结果不准确。 内存对齐(Memory alignment):在C语言中,结构体和数组等数据类型的...

假设a和b是非负的,并且b小于INT_MAX / 2,下面是一个简单的实现:
Integer division by zero (FPE_INTDIV) and integer overflow (FPE_INTOVF) are also included among the SIGFPE types, but because they are not IEEE floating point exceptions you cannot install handlers for them via ieee_handler. (You can install handlers for these SIGFPE types via sigfpe(3); ...
