    Description

      The bug

      The /teleport doesn't seem to check the number bounds anymore. Compare to 1.12, teleporting past 30 million is not possible and 1e1000 is not considered a valid value.

      You can also teleport things to NaN, which also fails to parse as a valid coordinate in 1.12.

      How to reproduce

      Issue the following commands:

      /summon armor_stand
      /teleport @e[type=armor_stand] ~ ~ 1e1000
      

      Teleported Armor Stand to something, something, Infinity appears in chat. The armor stand does not move.
      → The server freezes (chunkloading doesn't work, chat unresponsive, you know the drill)
