Fixed decimal point display is selected by pressing [0sP] []
followed by the appropriate number key to specify the number
of decimal places (0-9) to which the display is to be rounded.
Fixed point display allows answers to be shown with the same
number of places after the decimal point. The number begins
at the left side of the display and includes trailing zeros within
the setting selected. When the calculator is turned OFF, then
ON, it always returns back to fixed point notation with the
display rounded to two decimal places.
