Players Y coordinate is incorrect at Y 1 and 2 when stood on top of a block

When stood on top of blocks solid blocks at a y level 0 (player at y 1) and y 1 (player at y 2) the players y position returns a floating point value rather than an integer value like when stood on top of a solid block at any other y level.

In the image I am using the script API to print the players exact Y coordinate. Also trying to set a block at the players exact coordinate with the script API will result in the block being placed below the player instead.
