类型转换意味着将变量从一种数据类型转换为另一种数据类型。当大字体转换为小字体时, 该值可能会丢失。
转到类型转换示例
package main
import (
"fmt"
"strconv"
)
func main() {
var i int = 10
var f float64 = 6.44
var str1 string = "101"
var str2 string = "10.123"
fmt.Println(float64(i))
fmt.Println(int(f))
newInt, _ := strconv.ParseInt(str1, 0, 64)
fmt.Println(newInt)
newfloat, _ := strconv.ParseFloat(str2, 64)
fmt.Println(newfloat)
}
输出:
10
6
101
10.123
