eval command with a numeric return value causes exception

[ethul]

When I attempt to return a numeric value from a Lua script, I arrive at the following exception.

Thanks for reporting .. will address shortly

[debasishg]

Looks like the return type of a Lua script in Redis varies depending on the type that Lua returns. Will explore soon and come up with a solution.
