in thread Float/double to hex?

Well, FWIW, seems to poop it out just fine

I figure it is but I can't get it correct

I can get on my machine (3eaa aaab ≈ 1/3) with

$ perl -le " print unpack 'H*', pack 'f>', 1/3 3eaaaaab
but basically I tired brute forced it :)

I also saw these and they might have something to do with it, but the bits got me :) Network IEEE 754 to Native Floats: which pack/unpack ops better?, Extracting IEEE 754 floating point numbers

    I've no idea what that hex value is, but it certainly isn't any IEEE representation of 1/7.
