in thread Use pack to create a float in non-native format

Well, I tried it (actually needed single-format floats i.e. 32-bits, so adjusted accordingly) - my guess is that the bits were reversed from what they needed to be. Which brings me on to the next response...

    I didn't think to try the built-in big-endian conversion, because you said you'd already tried reversing the bytes. And that's all it does.

    I missed that you'd forgotten the scalar context requirement: 

    print unpack 'H*', pack 'f>', 123.456;;
42f6e979

print unpack 'H*', scalar reverse pack 'f', 123.456;;
42f6e979
