Functions

typename = mongo.type(obj)

Returns a string name of the BSON type of obj. If obj is not a BSON object, returns the standard Lua type name.

num = mongo.tonumber(obj[, base])

Returns the number value represented by BSON data obj. If the value of obj cannot be converted into a number returns nil.

If obj is not a BSON data object behaves exactly the same as Lua's builtin tonumber.
