python - converting negative float numbers to unsigned int -

-

im trying send unsigned int data c server python client. requirement send negative float value client. number -5.700 , have 2 problems. 1) dont have clue on how retain negativeness within uint32_t, im using msb flag bit around it. fine? has better suggestions?

2) tried typecasting float 5.700 uint32_t, i.e uint32_t fops = *(uint32_t*)(&float_var) //float_var 5.700 , fops assigned value 0x00..40b66666 being sent python client. how retrieve float value @ client?

update: mats suggested python struct unpacks -ve floats there no need use flag bit.

the simplest solutions best: make string, , transfer that, rather binary floating point representation. way, don't have worry differences in floating point representation or how make python "understand" binary floating point value.

edit1: however, if transfer 32-bit integer python data object: expect floatdata = struct.unpack("f", data) should trick.

edit2: documentation struct.unpack (and struct.pack)

edit3: struct.unpack assume both machines use same floating point format. means software isn't portable. should work ok on commonly available platforms.
