将整数转换回32位十六进制表示形式然后进行浮点运算？

Question

Say I have some binary data that was converted to 32-bit integer instead of 32-bit floating point (little endian), how can I rectify this?

For example: 1155186688 should be 1750 float ( 00 C0 DA 44 hex).

Answer 1

Struct is used for packing and unpacking types into bytes.

Convert the integer back to bytes, then into a float:

struct.unpack('f', struct.pack('I', 1155186688))[0]

Or the long form:

>>> my_bytes = struct.pack('I', 1155186688) # 'I' = Unsigned Int
b'\x00\xc0\xdaD'
>>> my_float = struct.unpack('f', my_bytes)[0] # 'f' = float
1750
