Query / Problem:
Ok, can someone help me out?  I am trying to create formula that is going to round my numbers to x.47 or x.97.
So what I am trying to do is to take discount from price and if it ends x.49 I would like to round it x.47 and if it ends x.99 I would like to round it to x.97. Does this make sense….so everything between x.51 and x.99 should be rounded to x.97 and everything between x.01 to x.49 should be rounded to x.47. 


Assuming the contents as follows
Column A (Actual Price) - A1 = 9.99
Column B (Discount)      - B1 = 75%
Column C (Sale Price)    - C1 = '=A1*(1-B1)'

The Solution would be
Column D (Tag Price)     - D1 = '=FLOOR(C2,1)+IF(CEILING(C2,1)-(C2)<0.5,0.97,0.47)'
