Enchant tl.moveTo target position not precise

Hi, thank you for making this awesome framework.

I wanted to ask, is tl.moveTo or moveBy target position is intended to not precise ?
because my last project use tween animation and then calculate based on exact position, but because not exact i had to do math.floor or change to target with .then() after tl . If this was a bug, please fix 

Thank you
