I am doing some calculation to find the produt price, after doing the calculation I would want the total cost to end as .99
for ex: Return (valel / 1.9) + ((13.95 / 1.9) + (56 + 1.9)) X 9
if the result for the above come as 54.30 then I would want it to come as 54.99
or 54.01 to 54.99
or 54.98 to 54.99
Can someone please help in this?
