我尝试编译一个使用SSE2的intel提供的随机数生成器函数.如果我尝试编译以下代码:

我正在尝试解组从Web服务获得的一些json数据.我已经简化了下面代码中显示的问题.我的问题是我可以在代码工作中制作版本(c).

我知道它适用于单个数字值,如"timestamp"所示,方法是在json注释中添加选项",string".但我无法弄清楚这是如何或是否适用于字符串编码数字的数组.(参见代码中列出的示例json中的"转换")

package main

import (
    "encoding/json"
    "fmt"    
)

//version (a)
type JsonData1 struct {
    TimeStamp   uint64          `json:"timestamp,string"`
    Conversions [][2]string     `json:"conversions"`
}

//version (b)
type JsonData2 struct {
    TimeStamp   uint64              `json:"timestamp,string"`
    Conversions [][2]json.Number    `json:"conversions"` 
}

//version (c)
type JsonData3 struct {
    TimeStamp   uint64          `json:"timestamp,string"`
    Conversions [][2]float32    `json:"conversions"` 
}

const incomingJson string = `{"timestamp": "1407178369", "conversions": [["1.021", "2.124"], ["2.432", "3.923"], ["3.234", "5.001"]]}`

func main() {
    var data1 JsonData1
    if err1 := json.Unmarshal([]byte(incomingJson), &data1); err1 != nil {
        fmt.Println("Error unmarshaling with struct …
