I registered for this and got 5,000.999999 Stellars. Kinda curious about the 0.999999 part...
(which would be silly, so there must be another reason! :-)

They must have been transferring +1 Stellar to cover the transaction fee. An 5k balance looks better than 4999.
Maybe the values are stored as a float? But that would be silly, so there must be a better reason.
