I had another question. If you paid $100,000/12 and used a float. Why would the result be exactly $100,000? Why wouldnt the float (or decimal) round up or down everytime someone is paid? I am talking about when writing a cheque (you cant do 1/2 or 1/3 a cent) or a direct deposit (i assume it has the same limitations)
