    Description

      Trivial to reproduce, just set a field to a string, then try to multiply it and you get the $inc error:

      db.foo.update({}, {$mul : {a : 2}}, false, {multi : true}, {ordered : false})
      Update WriteResult({
      	"ok" : 1,
      	"nDocsModified" : 0,
      	"n" : 0,
      	"writeErrors" : [
      		{
      			"index" : 0,
      			"code" : 16837,
      			"errmsg" : "Cannot apply $inc to a value of non-numeric type. {_id: ObjectId('52d44e8d4166d7524db9bd2d')} has the field 'a' of non-numeric type String"
      		}
      	]
      })

      Proposed fix (needs validation):
