WebAug 14, 2012 · A straight-forward way to obtain the bytes is to create a C union of float or double and an appropriate-length array of unsigned char. Store the float value into the union and then retrieve the unsigned char bytes for conversion to hex. You can also use casts of the appropriate pointer types to perform this "aliasing". WebFeb 9, 2015 · float in Python is actually what C programmers call double, i.e. it is 64 bits (or perhaps even wider on some platforms). So when you store it in 4 bytes (32 bits), you lose precision. If you use the d format instead of f, you should see the results you expect: >>> struct.unpack ('d', struct.pack ('d', float ('0.931973'))) (0.931973,) Share Follow
