常用基本类型的转换方法比较简单,我们这里使用一个例子来演示转换方法的使用及效果。

    更多的类型转换方法请参考接口文档:https://godoc.org/github.com/gogf/gf/util/gconv

    1. package main
    2. import (
    3. "fmt"
    4. "github.com/gogf/gf/util/gconv"
    5. )
    6. func main() {
    7. i := 123.456
    8. fmt.Printf("%10s %v\n", "Int:", gconv.Int(i))
    9. fmt.Printf("%10s %v\n", "Int8:", gconv.Int8(i))
    10. fmt.Printf("%10s %v\n", "Int16:", gconv.Int16(i))
    11. fmt.Printf("%10s %v\n", "Int32:", gconv.Int32(i))
    12. fmt.Printf("%10s %v\n", "Int64:", gconv.Int64(i))
    13. fmt.Printf("%10s %v\n", "Uint:", gconv.Uint(i))
    14. fmt.Printf("%10s %v\n", "Uint8:", gconv.Uint8(i))
    15. fmt.Printf("%10s %v\n", "Uint16:", gconv.Uint16(i))
    16. fmt.Printf("%10s %v\n", "Uint32:", gconv.Uint32(i))
    17. fmt.Printf("%10s %v\n", "Uint64:", gconv.Uint64(i))
    18. fmt.Printf("%10s %v\n", "Float32:", gconv.Float32(i))
    19. fmt.Printf("%10s %v\n", "Float64:", gconv.Float64(i))
    20. fmt.Printf("%10s %v\n", "Bool:", gconv.Bool(i))
    21. fmt.Printf("%10s %v\n", "String:", gconv.String(i))
    22. fmt.Printf("%10s %v\n", "Bytes:", gconv.Bytes(i))
    23. fmt.Printf("%10s %v\n", "Strings:", gconv.Strings(i))
    24. fmt.Printf("%10s %v\n", "Ints:", gconv.Ints(i))
    25. fmt.Printf("%10s %v\n", "Floats:", gconv.Floats(i))
    26. fmt.Printf("%10s %v\n", "Interfaces:", gconv.Interfaces(i))
    27. }

    执行后,输出结果为:

    1. Int: 123
    2. Int8: 123
    3. Int16: 123
    4. Int32: 123
    5. Int64: 123
    6. Uint: 123
    7. Uint8: 123
    8. Uint16: 123
    9. Uint32: 123
    10. Uint64: 123
    11. Float32: 123.456
    12. Float64: 123.456
    13. Bool: true
    14. String: 123.456
    15. Bytes: [119 190 159 26 47 221 94 64]
    16. Strings: [123.456]
    17. Ints: [123]
    18. Floats: [123.456]
    19. Interfaces: [123.456]
