Need to bring back separate ways to track entity health.

before the snapshots for 1.9, you were able to test for two different types of entity data relating to health, those being health, and healf. healf would send back a float number and health would send back an integer or a whole number. this needs to be brought BACK. or at least change the new health data to be a whole number. testing for entity health has never been harder due to the fact that you need over 20,000 command blocks to find the health of something from a range of 0-20.
