Any way to align an entity to all axises in minecraft bedrock?

There are two ways you could do this. The first is to just summon the entity at the correct place, as everyone else has been telling you (I will use a sheep for the remainder of this)

/summon sheep 23 24 25

instead of

/summon sheep ~ ~ ~

The other way you could do it is to take advantage of a shulker's auto-align feature. You can summon a shulker, it will align automatically to the axis'. You can then execute as the shulker, and summon a sheep at it. Example:

/execute @e[type=shulker,c=1] ~ ~ ~ summon sheep

After this, you just kill the shulker.
