I've read some bytes from a file and just now I can't interpret 4 bytes
in this dates like a real value. An extract from my program:
def l32(c):
return ord(c[0]) + (ord(c[1])<<8) + (ord(c[2])<<16) + (ord(c[3])<<24)
...
value = l32(f.read(4)) <--- 3F 8C CC CD should be 1.11
OK, here's the skinny (I used blocks & views to get the answer):
import struct
bytes = ''.join(chr(int(txt, 16)) for txt in '3F 8C CC CD'.split())
struct.unpack('>f', bytes)
I was suspicious of that first byte, thought it might be an exponent,
since it seemed to have too many on bits in a row to be part of 1.11.
