When attempting to use the execute align command, I noticed a major problem with it. I assumed it was meant to align summoned entities at the center of a block. However, testing on an armor stand with the command (/execute at @a align x align z run summon minecraft:armor_stand) I noticed the armor stand opts to summon at the top left corner of the block rather than the center. This is because the center of the block is 0.5 where it should be 0.0. If you teleport yourself to 0 ~ 0 it puts you at the center of the block. If you teleport yourself to 0.5 ~ 0.5 it also teleports you to the center of the block, thus making 0.5 = 0? To me, this makes no sense. 0.0 should be the center of the block.
