聚合类型的算法 [英] Arithmetic on aggregated types

问题描述

嗨论坛，



有没有人知道有关聚合类型算术的资源？



我正在使用这样的附加：

Hi forum,

does anyone know of a resource covering arithmetic on aggregated types?

I'm using addition like this:

typedef struct
{
    uint8_t hb;
    uint8_t mb;
    uint8_t lb;
}BunchOBytes;

BunchOBytes Add(BunchOBytes in0, BuncOBytes in1)
{
    BunchOBytes result;
    uint16_t sum;

    sum = in0.lb + in1.lb;
    result.lb = sum;
    sum >>= 8;
    sum += in0.mb + in1.mb;
    result.mb = sum;
    sum >>= 8;
    sum += in0.hb + in0.hb;
    result.hb = sum;

    return(result); // handle overflow
}

现在我需要了由标量划分。任何人都可以推荐这本书吗？

Now I'm in need of division by a scalar. Can anyone recommend a book on this?

推荐答案

似乎你不想使用 enum 但是结构：

It seems that you don't want to use an enum but a structure:

typedef struct
{
    unsigned hb;
    unsigned mb;
    unsigned lb;
}BunchOBytes;

这篇关于聚合类型的算法的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
