Python:没有无符号数概念,因为int是高精度数,可以认为范围无穷,所以相当于是用signed Java:没有无符号数基本类型,数组长度只能用int(int是32bit的,不能用long会导致数组大小受限问题,不过跟今天说的无关) Go:同时支持各种有符号和无符号类型,但标准库的长度和代码风格基本都用的int C/C++:大部分时候使用size_t...
如果要输出 short int 的话使用%hi 或者%hd 输出 unsigned 和 signed unsigned 无符号修饰 signed 有符号修饰 /* signed unsigned */// 如果给变量前面加上 signed 修饰符的话,代表当前变量的取值范围是正数,负数,零// 就代表把二进制的最高位作为符号位,默认是有 signed 的修饰的signedintnum =9;// 如果...

🐛 Describe the bug Torch tensors have .is_signed property. As of 2.2.0, it works for all integer dtypes, (e.g. torch.uint8.is_signed is False). PyTorch 2.3.0 introduced new unsigned types (which is awesome!), but they do not support is_s...

一篇关于整数overflow的好文章:Implicit Overflow Considered Harmful (and how to fix it)。 BTW,其实「古代」语言如Ada就是会对overflow直接报错的。在现代语言中,Swift回归了这一传统。脚本语言中,JS直接用double来规避问题(但浮点数引入了更多问题),Python则是溢出自动变成大整数(这似乎是smalltalk和一些lisp实现早...
So signed isn't redundant as sometimes you need to define a signed or unsigned char. But is int redundent!? You can define: signed int a; unsigned int b; long int c; short int d; Or skip to: signed a; unsigned b; long c; short d; So int is not needed, but it is probably...
