[erlang-questions] float_to_binary?

[Steve Davis]

I'm probably being dumb, but I am stuck...

to_binary(X) when is_integer(X) -> <<X>>;
to_binary(X) when is_float(X) -> ??.

...btw attempting to use erlang:float_to_binary(X, 64) turned out to be 
a very bad idea (computer just went POP!).

Thanks for any assistance!
