Python byte数组和float、Int 互相转换 struct pack unpack

def byte2float(x):
    return struct.unpack('=d', x)[0]

def float2byte(f):
    return [hex(i) for i in struct.pack('f', f)]

def int2byte(f):
    return struct.pack('l', f)  # b'\xa0\xb3\xc3=\x0c\x00\x00\x00'


def new_float2byte(f):
    return struct.pack('d', f)


def byte2int(x):
    return struct.unpack('l', x)[0]

int is 35871268326178452 
b'\x94~9~\xbap\x7f\x00'           <int to byte>
2.7982836490718717e-306           <byte to float>
b'\x94~9~\xbap\x7f\x00'        <float to byte>
35871268326178452         <byte to int>
