大家好,又见面了,我是你们的朋友全栈君。 最近看代码里面涉及到 unit8_t 等数据类型,显然不是 C 原始数据类型,看名字猜测应该是使用 typedef 定义的。这样做主要是为了代码维护和移植时比较方便,比如C中没有bool,于是在一个软件中,一些程序员使用int,一些程序员使用short,会比较混乱,最好就是用一个typedef来定义,如:
在第一次学习go语言时,对go语言的各种int类型充满疑惑,为什么会有int、int8、int16等等的类型呢?为什么不像java一样,只个int类型呢?直接上demo
大家好,又见面了,我是你们的朋友全栈君 uint16 int c# C#Int16和C#UInt16 (C# Int16 and C# UInt16) In C#, Int16 known as UInt16,它是2个字节的无符号整数 ,只能存储0到65535范围之间的正值。 ‘Int16’和’UInt16’之间的区别 (Differences between ‘Int16’ and ‘UInt16’) Int16 UInt16 Int16 stands for signed Declaration syntax:Int16 variable; Declaration syntax:UInt16 variable; 16位 UInt16 Int16代表有符号整数。 Min: 0, Max: 65535 UInt16 array elements... -32768 0 1000 32000 32767 UInt16 array elements... 0 100
uint8_t / uint16_t / uint32_t /uint64_t 是什么数据类型

所以要调用 UInt16(one)来创建一个新的 UInt16 数字并用 one 的值来初始化,然后使用这个新数字来计算: let twoThousand: UInt16 = 2_000 let one : UInt8 = 1 let twoThousandAndOne = twoThousand + UInt16(one) 现在两个数字的类型都是 UInt16,可以进行相加。 目标常量 twoThousandAndOne 的类型 被推测为 UInt16,因为它是两个 UInt16 值的和。 在语言内 部,UInt16 有一个构造器,可以接受一个 UInt8 类型的值,所以这个构造器可以用现有的UInt8 来创建一个新的 UInt16。 注意,你并不能传入任意类型的值,只能传入 UInt16 内部有对应构造器的值。 2.
