因此引出 Go 中的 rune 类型,它可以代表一个字符编码的int32的表现形式,就是说一个字符用一个数字唯一标识。有点像 ASCII 码一样 a => 97, A => 65 源码解释如下//rune is an alias for int32 and is equivalent to int32 in all ways. It isused, by convention, to distinguish character valuesf...
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 ...
