在32位的编译器上，unsigned int最大值:4294967295。c语言标准库中的limits.h头文件定义了unsinged int的最大值宏——UINT_MAX，可以直接使用printf函数将其打印出来。include<stdio.h> include <limits.h> int main(){ printf("unsigned int最大值:%u\n", UINT_MAX );return 0;} ...

对于int32和int8,SSE2还有cmpgt来比较大小,借助返回的mask做位运算还能做到minmax。SSE4.2也加入了对int64的比较支持,但signed和unsigned的比较显然不是同一回事…… 那么,就手动实现一个吧? 最简单粗暴的做法就是,放弃SIMD,拿出scalar手动做max。虽然SSE没提供cmp,但对于标量,x86的cmp还是很全面的。
For unsigned integer types, minValue() is 0. TR: It’s confusing for integer min to be a very negative thing, but min float being a small-magnitude positive value. KG: Need to check, make sure min says what we think it is. Otherwise, we have consensus for maxValue(). ...
unsigned int:这是一个无符号整数类型,其大小和范围取决于编译器和系统架构。通常,它的大小与处理器的位数相同(例如,在32位系统上,它通常是32位,在64位系统上,它通常是32位)。 关于数据丢失的问题,如果您尝试将一个较大的整数类型转换为较小的整数类型,那么在转换过程中可能...
