不是所有数据类型都能转换的,例如string类型转换为int肯定会失败,编译就会报错cannot convert xxx (type string) to type int64; 低精度转换为高精度时是安全的,高精度的值转换为低精度时会丢失精度。上面的变量d与e就是这种情况; 要跨大类型转换,例如string与int的互转,可以使用strconv包提供的函数 3.strconv包...
这样的代码是错误的,编译器会提示cannot convert p (type *int) to type *int64 指针的强制类型转换需要用到unsafe包中的函数实现 type ArbitraryType int type Pointer *ArbitraryType 1. 2. 从unsate.Pointer的定义如下,从定义中我们可以看出,Pointer的本质是一个int的指针: ...
