golang float32/64与[]byte互转

网络协议开发中经常需要将int、float、bool等转为二进制数据，float32、64 与[]byte处理：

import (
    "encoding/binary"
    "math"
)

func Float32ToByte(float float32) []byte {
    bits := math.Float32bits(float)
    bytes := make([]byte, 4)
    binary.LittleEndian.PutUint32(bytes, bits)

    return bytes
}

func ByteToFloat32(bytes []byte) float32 {
    bits := binary.LittleEndian.Uint32(bytes)

    return math.Float32frombits(bits)
}

func Float64ToByte(float float64) []byte {
    bits := math.Float64bits(float)
    bytes := make([]byte, 8)
    binary.LittleEndian.PutUint64(bytes, bits)

    return bytes
}

func ByteToFloat64(bytes []byte) float64 {
    bits := binary.LittleEndian.Uint64(bytes)

    return math.Float64frombits(bits)
}
