I figure it is https://en.wikipedia.org/wiki/Single-precision_floating-point_format but I can't get it correct
I can get https://en.wikipedia.org/wiki/Single-precision_floating-point_format#Single-precision_examples on my machine (3eaa aaab ≈ 1/3) with
but basically I tired brute forced it :)
$ perl -le " print unpack 'H*', pack 'f>', 1/3
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
