Rnd : The argument of this function is made a decimal value and then
rounded in accordance with the current number of display digits setting
(Norm, Fix, or Sci). With Norm 1 or Norm 2, the argument is rounded off
to 10 digits. With Fix and Sci, the argument is rounded off to the specified
digit. When Fix 3 is the display digits setting, for example, the result of
10 ÷ 3 is displayed as 3.333, while the calculator maintains a value of
