Floats (Doubles) Not Supported

[pulltab]

After extending examples/voltkv in the open source voltdb distribution to use strings as the primary key and double types as the value I attempted to store a value as follows:

crypto:start(), application:start(erlvolt).
erlvolt:add_pool(kv, [{"localhost", 21212}]).
erlvolt:call_procedure(kv, "Put", [{9, <<"key">>}, {8, 9.99}]).

This resulted in the following deserialization error:

{result,{voltresponse,{0,
                       <<0,0,53,0,0,0,0,0>>,
                       -2,
                       <<"Exception while deserializing procedure params, procedure=Put\njava.lang.RuntimeExcep"...>>,
                       128,<<>>,<<>>,10},
                      []}}

I then attempted to store the key/value as follows:

crypto:start(), application:start(erlvolt).
erlvolt:add_pool(kv, [{"localhost", 21212}]).
erlvolt:call_procedure(kv, "Put", ["key", 9.99]).

Which resulted in:

voltdb's wire protocol supports only 64 bit double values.

Increasing float binary representations to 64 bits seems to resolve this issue.
