将嵌套的字符串片解组为float32

package main

    "fmt"

    // 假设我们有一个嵌套的字符串切片
    nestedStrings := [][]string{
        {"1.1", "2.2", "3.3"},
        {"4.4", "5.5", "6.6"},
    }

    // 创建一个float32切片来存储转换后的结果
    var floatSlices [][]float32

    for _, strSlice := range nestedStrings {
        var floatSlice []float32
        for _, str := range strSlice {
            // 将字符串转换为float32
            num, err := strconv.ParseFloat(str, 32)
            if err != nil {
                fmt.Printf("Error converting string to float32: %v\n", err)
                continue
            }
            floatSlice = append(floatSlice, float32(num))

    }

    fmt.Println(floatSlices)
