基本类型转换

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。

  1. package main
  3. import (
  4.     "fmt"
  5.     "github.com/gogf/gf/g/util/gconv"
  6. )
  8. func main() {
  9.     i := 123.456
  10.     fmt.Printf("%10s %v\n", "Int:",        gconv.Int(i))
  11.     fmt.Printf("%10s %v\n", "Int8:",       gconv.Int8(i))
  12.     fmt.Printf("%10s %v\n", "Int16:",      gconv.Int16(i))
  13.     fmt.Printf("%10s %v\n", "Int32:",      gconv.Int32(i))
  14.     fmt.Printf("%10s %v\n", "Int64:",      gconv.Int64(i))
  15.     fmt.Printf("%10s %v\n", "Uint:",       gconv.Uint(i))
  16.     fmt.Printf("%10s %v\n", "Uint8:",      gconv.Uint8(i))
  17.     fmt.Printf("%10s %v\n", "Uint16:",     gconv.Uint16(i))
  18.     fmt.Printf("%10s %v\n", "Uint32:",     gconv.Uint32(i))
  19.     fmt.Printf("%10s %v\n", "Uint64:",     gconv.Uint64(i))
  20.     fmt.Printf("%10s %v\n", "Float32:",    gconv.Float32(i))
  21.     fmt.Printf("%10s %v\n", "Float64:",    gconv.Float64(i))
  22.     fmt.Printf("%10s %v\n", "Bool:",       gconv.Bool(i))
  23.     fmt.Printf("%10s %v\n", "String:",     gconv.String(i))
  25.     fmt.Printf("%10s %v\n", "Bytes:",      gconv.Bytes(i))
  26.     fmt.Printf("%10s %v\n", "Strings:",    gconv.Strings(i))
  27.     fmt.Printf("%10s %v\n", "Ints:",       gconv.Ints(i))
  28.     fmt.Printf("%10s %v\n", "Floats:",     gconv.Floats(i))
  29.     fmt.Printf("%10s %v\n", "Interfaces:", gconv.Interfaces(i))
  30. }

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]
