Converting between types is done via a function with the name of the type to convert to. Golang没有类型的自动转换,需要手动转换类型。也就是说不能拿float乘int var x int = 42 // x has type int f := float64(x) // f has type float64 (ie. 42.0) var y float64 = 11.9 // y has...

普通变量类型int,float,string 都可以使用 type (a)这种形式来进行强制类型转换,比如 var a int32 = 10 var b int64 = int64(a) var c float32 = 12.3 var d float64 =float64(c) 1. 2. 3. 4. golang中 指针也是有类型的, package main ...
