Percentage Functions
The percentage functions are special (compared with  and  ) because they
preserve the value of the base number (in the Y–register) when they return the result
of the percentage calculation (in the X–register). You can then carry out subsequent
calculations using both the base number and the result without reentering the base
number.
Example:
Find the sales tax at 6% and the total cost of a $15.76 item.
Use FIX 2 display format so the costs are rounded appropriately.
