Nevermind, I just figured it out, but for the benefit of anyone searching this, I'll explain how I fixed it.
First, I went into the inspector and allowed 1 decimal place because the way I fixed it doesn't need the handicap cell to round up automatically. i.e. saying 13.8 is just fine.
Next, I created another column to the right of the handicap column and used the ROUNDUP function.
So, if the value of C2 is 13.8, then the formula in D2 would be "ROUNDUP(C2,0)". The C2 is the cell it takes the value from to round up, the 0 is how many decimal places the resulting value should have. Since I want a whole number, the decimal value is set to 0.
The next column that divides that number in half now divides the whole number instead of the decimal.
