I need to be able to round numbers down every time. We allocate 1 eight hour
employee for every 20000 SQ feet, jobs are given in 2 hour increments.

EX:
20000 Sq feet would equal 1 eight hour employee
29000 Sq feet = 1.45 not enough for another 2 hour employee so my answer
would need to be 1.0
25000 Sq feet would equal 1 eight hour employee and 1 two hour employee
