Convert byte slice “[]uint8” to float64 in GoLang

For example,

package main

import (
    "encoding/binary"
    "fmt"
    "math"
)

func Float64frombytes(bytes []byte) float64 {
    bits := binary.LittleEndian.Uint64(bytes)
    float := math.Float64frombits(bits)
    return float
}

func Float64bytes(float float64) []byte {
    bits := math.Float64bits(float)
    bytes := make([]byte, 8)
    binary.LittleEndian.PutUint64(bytes, bits)
    return bytes
}

func main() {
    bytes := Float64bytes(math.Pi)
    fmt.Println(bytes)
    float := Float64frombytes(bytes)
    fmt.Println(float)
}

Output:

[24 45 68 84 251 33 9 64]
