Hi, Well not a complaint as such but a question. Thank you for the response however and the link. I have seen it before but never got around to reading it...
Further to this, if i was writing a python module and c function and suppose the python module and the c function called each other back and forth exchanging results from float calculations - would not the results then become flawed? How would one pass floats between different languages - using special purpose data structures understood by both the python module and c code? I asked this question without reading the link, so if it stinks of ignorance please forget it.
