Percentage Functions (%, %CHG)
The percentage functions are special (compared with 0 and (T|) be
cause 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.
To Calculate:
Key In:
x% of y
Percentage change from y to x. (y ¥= 0)
