Spawning particles on precise xyz coords of player

I'm making an armour set, and i made it so when you have a full set, it spawns particles on you depending on the armour. However the particles only spawn at the corner of the block where the player is standing probably because MCreator uses xyz as integers (1, 5, 12) and not floats (1.52, 5.64, 12.22). Is there a way to make the particles spawn directly on the player?
